Sora Minamoto Mainnet

SORA Minamoto Mainnet

Use the Minamoto mainnet through native Torii MCP.

Quick Start

1. Confirm a Minamoto MCP server is available in the current Codex environment.
2. Treat https://minamoto.sora.org as the primary public Torii/API origin and https://minamoto.sora.org/v1/mcp as its native MCP endpoint.
3. Before long or stateful workflows, sample public health first. Prefer proceeding only when blocks are advancing, queue_size is low, tx_queue_saturated=false, and teu_dataspace_backlog is not climbing.
4. Prefer curated iroha.* tools over raw torii.* tools.
5. Stay read-only until the user explicitly asks to mutate live mainnet state.
6. Treat any signing inputs, API tokens, or forwarded auth headers as runtime-only secrets.
7. Do not use Taira testnet faucet, bootstrap, or canary assumptions on Minamoto.
8. When the user asks to transact, follow the "Transaction Workflow" section before submitting anything.
9. In Codex sessions where multiple SORA MCP servers are available, use the Minamoto namespace or server entry for Minamoto work. Do not call Taira tools for Minamoto state.

MCP Endpoint

Use the public Minamoto MCP endpoint:

• https://minamoto.sora.org/v1/mcp

The matching public Torii/API root is:

• https://minamoto.sora.org

If the endpoint is not configured locally, instruct the user to add a user-local MCP entry that points at that URL:

codex mcp add sora-minamoto-mainnet --url https://minamoto.sora.org/v1/mcp

If the endpoint returns 404, report that native Torii MCP is not enabled on the Minamoto deployment yet and stop before attempting live-network actions.

If the MCP endpoint or the public Torii root returns 502 or 503, report public ingress / rollout health degradation before attempting writes. Treat that as deployment health, not user input failure.

If reads work but live writes fail with route_unavailable, report that the public ingress still cannot reach authoritative peers for the target lane. Do not classify that as a malformed payload without operator-side evidence.

If writes fail with Transaction expired, classify that as chain health, consensus latency, or queue saturation first. Sample /status and /v1/sumeragi/status and report the current blocks, commit_qc_height, highest_qc_height, queue_size, tx_queue_depth, tx_queue_saturated, teu_dataspace_backlog, and view_change_causes.last_cause before blaming the caller.

Restart Smoke Test

After installing or updating this skill and restarting Codex, verify the live mainnet wiring with read-only calls only:

1. Confirm the configured MCP server points at https://minamoto.sora.org/v1/mcp.
2. Confirm a Minamoto MCP namespace or server entry is visible in the current session.
3. Call iroha.sumeragi.status and check that commit_qc.height is present, tx_queue.saturated=false, and queue depth is low.
4. Fetch the latest known block with iroha.blocks.get.
5. List recent transactions with iroha.transactions.list, then check one listed hash with iroha.transactions.status.
6. Optionally call a Musubi read such as iroha.musubi.alias.resolve; a 404 not_found means that alias is absent, not that the tool is broken.

Do not use broad alias-index enumeration as a health check. It may be permission-bound on Minamoto and can legitimately return 403 permission_denied.

Working Rules

1. Prefer iroha.* aliases. They are the intended agent-facing surface for deployed networks.
2. Use explicit JSON body payloads when a write flow needs more than a couple of flat shortcut arguments.
3. Keep authority, private_key, bearer tokens, and forwarded auth headers out of files, docs, and commits.
4. Before any Minamoto write, verify the signer on-chain first: the account exists on the current Minamoto chain, holds the required fee asset balance, and has the permissions required for the specific mutation.
5. Prefer pre-signed transaction envelopes from the user's wallet or client for value-moving or irreversible mainnet operations.
6. Never run testnet onboarding, faucet, or throwaway canary flows against Minamoto unless the user explicitly asks for that exact mainnet operation.
7. Do not reuse Taira or zero-chain client configs for Minamoto. Use an operator-provided or user-local Minamoto config and keep it out of the repo.
8. For pre-signed transaction envelopes, use iroha.transactions.submit_and_wait.
9. If a mutation would affect live state, apply the "Mainnet Write Confirmation Policy" before executing it.
10. For Musubi package-registry writes, use the pre-signing helpers only when they are exposed by the Minamoto MCP server: iroha.musubi.instructions.publish_release, iroha.musubi.instructions.yank_release, iroha.musubi.instructions.set_alias, and iroha.musubi.instructions.assert_release_exists. They return unsigned Norito-framed instructions; sign and submit them from the client side.

Minamoto vs Taira Differences

Transaction Workflow

Use this sequence for any Minamoto mutation, including asset transfers, contract calls, governance changes, package-registry writes, alias changes, or account operations:

1. Discover the available MCP tools and prefer the curated iroha.* names. Re-check inputSchema for every tool used in the flow.
2. Sample public health:
   • GET https://minamoto.sora.org/status
   • iroha.status
   • iroha.sumeragi.status
3. Identify the signer:
   • resolve the user-provided alias with iroha.aliases.resolve, when an alias was supplied
   • fetch the canonical account with iroha.accounts.get
   • inspect fee balances with iroha.accounts.assets
   • inspect the required permission state with the narrowest available iroha.* permission or account query
4. Identify the target state:
   • fetch the target account, asset definition, contract instance, package, or governance object before building the write
   • record current values needed to verify the post-write state
5. Build the unsigned instruction or transaction body using the specific iroha.* helper, or ask the user's wallet/client to build it.
6. Get a signature outside Codex by default. Prefer a user-provided signed_tx_base64 envelope over raw private-key signing in the agent session.
7. Before submission, apply the "Mainnet Write Confirmation Policy".
8. Submit the pre-signed envelope with iroha.transactions.submit_and_wait.
9. Verify final state with a read query against the object changed by the transaction.
10. Report the transaction hash, final status, block height if available, the verification query result, and any uncertainty caused by public-node visibility.

Mainnet Write Confirmation Policy

Before submitting a transaction that mutates Minamoto, restate the intended change in concrete terms. The confirmation summary should include:

• signer alias and canonical account id, when known
• target account, asset, contract, package, governance object, or alias
• exact operation and parameters
• fee or gas asset metadata, when required by the chain or tool
• whether value moves between accounts
• whether the operation is irreversible or difficult to reverse
• expected verification query after submission

For value-moving or irreversible operations, do not submit until the user confirms after seeing this summary, unless the user already supplied a signed envelope and a clear submit-now instruction in the current request. If any item is ambiguous for a value-moving or irreversible operation, ask for clarification before submission.

Required User Inputs for Writes

For a Minamoto write, collect or confirm these inputs before spending time on payload debugging:

• signer alias or canonical account id
• target object id, such as an account id, asset id, contract id, package id, governance proposal id, or alias
• operation parameters, including amounts, metadata keys, arguments, or package version details
• either a pre-signed transaction envelope, or an unsigned instruction/body plus an external signing path
• Minamoto public root/MCP endpoint or an explicit operator-provided root if the default public endpoint is not the target
• fee or gas asset metadata if the deployment requires it
• timeout expectations for submit_and_wait
• expected post-write read query

If the user supplies a local client config, treat it as runtime-only. Do not copy it into the repo or quote secrets from it.

Do Not Sign Inside Codex By Default

For Minamoto, the default write path is:

1. inspect state
2. prepare or validate the unsigned operation
3. ask the user's wallet/client to sign
4. submit the pre-signed envelope
5. verify state

Do not ask for raw private keys, mnemonic phrases, bearer tokens, or forwarded auth headers for mainnet work unless the user explicitly insists on that path. If the user insists, treat the values as runtime-only secrets: do not persist them, do not echo them, do not put them in docs, and do not commit them.

If a tool accepts authority and private_key, do not assume that makes agent-side signing appropriate on mainnet. Prefer pre-signed envelopes for value-moving or irreversible operations.

Public-Node Diagnostics

1. Treat https://minamoto.sora.org as the default public Torii vantage point for Minamoto. It is still only one public view, not proof of full validator-set health.
2. Do not invent or assume direct per-validator public hostnames. They may exist on some deployments and may be intentionally absent on others.
3. Do not infer validator-set size from /status.peers. That field is the queried node's current remote-peer count, not the network's validator-set length.
4. When diagnosing public-write or finality issues, prefer this read bundle:
   • iroha.status
   • iroha.sumeragi.status
   • iroha.blocks.list
   • iroha.transactions.status or iroha.transactions.wait
   • GET https://minamoto.sora.org/status
5. If the latest committed block timestamp stops advancing and Sumeragi shows signals such as membership.height > commit_qc.height, view_change_causes.last_cause = "missing_qc", or view_change_causes.last_cause = "quorum_timeout", or worker_loop.stage = "idle", report that the queried public Torii finality path appears stalled. Do not claim the entire validator set is down unless you also have direct validator or operator visibility.
6. If iroha.transactions.status returns 404 not_found for a previously submitted hash, report only that the queried public node currently has no visibility for that transaction hash. Do not infer commit, reject, or network-wide disappearance from that result alone.
7. If public reads are healthy but signed writes still expire, call that a partial public-node or public-finality-path failure first, not proof that the user payload is malformed.

Known Failure Patterns

1. route_unavailable while public reads still work usually means the public ingress can answer read traffic but cannot reach an authoritative peer for the target write lane. Treat that as rollout health first.
2. Transaction expired on signed writes usually points at chain health, consensus latency, queue saturation, or public finality trouble before it points at malformed user input.
3. 502 or 503 from /v1/mcp or the public Torii root usually means edge or upstream rollout breakage, not a signer or payload problem.
4. Permission or fee failures on mainnet should be reported narrowly with the signer, target account, required permission, and fee asset evidence that the public node returned. Do not try to self-fund or auto-onboard a mainnet signer.

Failure-to-Action Map

Preferred Triage Sequence

1. Start with read-only public health:
   • GET https://minamoto.sora.org/status
   • iroha.status
   • iroha.sumeragi.status
2. Confirm the MCP server exposes the expected curated tools before choosing a workflow:
   • iroha.status
   • iroha.transactions.submit_and_wait
   • the specific iroha.* account, alias, asset, contract, governance, or Musubi tools required by the request
3. For any write, preflight the signer and target state with read-only queries.
4. Prefer a user-provided pre-signed transaction envelope for irreversible or value-moving changes.
5. Only spend time on payload debugging after public health, signer existence, signer balance, and signer permissions are confirmed.

MCP Write Recipes

Submit a pre-signed transaction envelope

For pre-built signed transactions, prefer iroha.transactions.submit_and_wait instead of lower-level polling:

{
  "signed_tx_base64": "<base64-encoded SignedTransaction>",
  "status_accept": "application/json",
  "timeout_ms": 120000
}

Verify a signer before writes

Before submitting any Minamoto mutation, confirm the alias, account, fee balance, and permissions before debugging payloads:

• resolve the alias with iroha.aliases.resolve
• fetch the canonical account with iroha.accounts.get
• inspect balances with iroha.accounts.assets
• inspect permission state with the narrowest available iroha.* account or permission query tool exposed by the deployment

If the signer is missing, has no fee asset balance, or lacks a required permission, report that directly. Do not run faucet or bootstrap flows on mainnet.

End-to-end signed-envelope write

Use this shape after the user or their wallet/client provides the signed transaction envelope:

{
  "signed_tx_base64": "<base64-encoded SignedTransaction>",
  "status_accept": "application/json",
  "timeout_ms": 120000
}

After submission, run the specific verification read for the changed object. For example, verify balances after a transfer, metadata after a metadata mutation, package release state after a package write, and contract instance state after a contract call.

Inspect Musubi packages

Use the curated Musubi tools for package reads when the Minamoto MCP server exposes them:

• iroha.musubi.search with query, optional namespace, include_yanked, offset, and limit
• iroha.musubi.release.get with package = "namespace/name@version"
• iroha.musubi.package.releases with package = "namespace/name" and optional include_yanked
• iroha.musubi.package.versions with package = "namespace/name"
• iroha.musubi.alias.resolve with alias = "<short-name>"

Musubi namespaces intentionally do not use a leading @; use literals like universal, dex.universal, and dex.universal/swap-core when those namespaces exist on Minamoto.

Build Musubi instructions for local signing

The Musubi instruction tools do not accept authority, private_key, bearer tokens, or any other signing material. They return wire_id, instruction_base64, instruction_hex, and an instruction_json preview. The client must assemble a signed transaction locally and submit it with iroha.transactions.submit_and_wait.

Use signed_tx_base64 or tx_base64 for base64 envelopes, or the hex variants for hex-encoded envelopes. Do not pass multiple envelope encodings in the same request. If the call returns Transaction expired, go back to the public health and Sumeragi checks before rebuilding the transaction.

Common Mainnet Read Recipes

Use these as starting payload shapes, then adjust to the tool's inputSchema if the deployment exposes a slightly different field name.

Health

Tool: iroha.status

{}

Tool: iroha.sumeragi.status

{}

HTTP:

GET https://minamoto.sora.org/status

Alias resolution

Tool: iroha.aliases.resolve

{
  "alias": "<label@dataspace>"
}

Account lookup

Tool: iroha.accounts.get

{
  "account_id": "<canonical-account-id>"
}

Account assets and fee balance

Tool: iroha.accounts.assets

{
  "account_id": "<canonical-account-id>"
}

Asset lookup

Tool: iroha.assets.get

{
  "asset_id": "<asset-id>"
}

Asset definition lookup

Tool: iroha.asset-definitions.get

{
  "asset_definition_id": "<asset-definition-id>"
}

Recent blocks

Tool: iroha.blocks.list

{
  "limit": 10
}

Recent transactions

Tool: iroha.transactions.list

{
  "query": {
    "limit": 10
  }
}

Some deployments expose flat shortcuts such as limit, but explorer pagination may still return the default page size. Always inspect the returned pagination object and the discovered inputSchema before assuming a shortcut was honored.

Transaction status

Tool: iroha.transactions.status

{
  "hash": "<transaction-hash>"
}

Wait for a transaction

Tool: iroha.transactions.wait

{
  "hash": "<transaction-hash>",
  "timeout_ms": 120000
}

Contract instance lookup

Use the deployment's discovered contract read tool. Common names may include iroha.contracts.instance.get or a contract-specific query tool; confirm the actual name and schema with tool discovery before calling it.

Response Handling

1. Use each tool's inputSchema as the source of truth for accepted fields.
2. Re-run tool discovery if the MCP server reports that the tool list changed.
3. Prefer namespaced Minamoto tools when Codex exposes multiple SORA MCP servers in the same session.
4. When a write tool succeeds, summarize the resulting transaction hash or the returned status, not just the request payload.
5. When a write tool fails, surface the server error and say whether the issue looks like auth, validation, missing tool exposure, or endpoint availability.
6. Treat route_unavailable as deployment health, not user input failure: the public Torii node is up but the write route still cannot reach an authoritative peer.
7. Treat 502 or 503 from the MCP endpoint or public Torii root as ingress or rollout-health failures first.
8. Treat Transaction expired as a likely stalled, saturated, or slow chain path first; report the public /status and /v1/sumeragi/status sample alongside the failure.
9. Treat 403 Forbidden as a likely signer-permission, authorization, route, or policy boundary first, not a malformed request.
10. Treat a Musubi 404 not_found as an absent alias/package when the Musubi tool itself is callable.
11. Treat ignored pagination shortcuts as a schema/pagination issue. Check the returned pagination object and retry with the schema-supported query shape before reporting surprising counts.
12. If public reads succeed but finality appears stalled, describe the issue as a public-node or public-finality-path observation unless you have validator-side evidence. Avoid overstating that as a full-network outage.

Agent Output Requirements

For read-only work, report:

• the public root or MCP endpoint used
• tool names used
• relevant block height or status sample timestamp when available
• the exact account, asset, contract, package, or transaction id queried
• any visibility limitation from querying only the public Minamoto endpoint

For submitted transactions, report:

• transaction hash
• final status returned by submit_and_wait or wait
• block height or committed block reference when available
• signer alias and canonical account id, when known
• target object and operation summary
• verification query and result
• any uncertainty, such as stale public reads or 404 transaction visibility

Safety

• Do not invent or claim pre-existing operator key material.
• Do not generate, onboard, or fund a Minamoto signer unless the user explicitly asks for that mainnet operation and understands it affects live state.
• Persist runtime credentials only when the user explicitly asks, and then keep them in ignored user-local files rather than tracked repo state.
• Do not assume operator-only routes are available on public Minamoto.
• Prefer anonymous/public reads first when investigating state.
• Prefer user-local MCP entries and configs for Minamoto; do not commit mainnet endpoint overrides, auth headers, or signing material into the repo.
