Agent Connector

agent-connector

agent-connector serves two distinct audiences. Pick the track first.

• MCP developer: building an MCP integration. They depend on @ken-jo/agent-connector, write defineConnector({...}), expose their own branded package/bin, and deploy to detected agent hosts through that brand.
• Agent-CLI user: not authoring a connector. They use agent-connector usage only, which scans agent host logs read-only and reports whole-conversation totals by CLI/model/project/session/day.

The accuracy boundary is strict: developer telemetry can measure per-MCP and per-tool tokens only for the developer's own wrapped stdio server. Connector-free usage cannot itemize arbitrary MCPs or tools because agent hosts do not log per-tool attribution.

Read The Right Reference

This skill is intentionally small. Read the relevant reference file before acting:

• references/package-first.md — required for any scaffold, code review, wizard, docs, or naming/identity decision. It defines the package-first contract and what not to ask the user for.
• references/authoring.md — required when creating or editing agent-connector.config.*, SDK imports, hooks, commands, skills, subagents, memory, statusline options/host overrides, action metadata/host overrides, or platform escape hatches.
• references/cli-workflow.md — required when wiring bin.mjs, install, uninstall, upgrade/sync/update, doctor, package, or marketplace/direct install flows.
• references/telemetry.md — required for any token, usage, leaderboard, privacy, opt-out, or "which MCP/tool costs tokens?" question.
• references/agent-readiness.md — required when improving agent-facing docs, skills, scaffold/boilerplate, lint/audit, MCP-server affordances, or other "make this easy for AI agents" surfaces.

For exhaustive field-level detail, use llms-full.txt; statusline and action SDK changes should specifically be checked against §2.5 and §2.6. For the short map, use llms.txt. For current host coverage and platform count, use the website /coverage page; do not copy a fixed count into this skill. The public website mirrors developer docs under /docs/dev.

Default Agent Procedure

1. Inspect the target package's package.json first.
2. Use package.json name, mcpName, bin, and version as the source of truth for MCP identity, host alias/display label, public command, and connector version.
3. Do not request separate connector id, display name, bin name, or version unless metadata is absent or the user explicitly needs a legacy/multi-instance override. When showing generated host configs, comment that host-native ids are install artifacts derived from package metadata, not second user-maintained inputs.
4. Import new authoring code from @ken-jo/agent-connector/sdk. For statusline/actions, use SDK capability introspection or the offline harness to confirm host behavior; unsupported hosts should be documented as disabled or skip-warn, not inferred support.
5. Put createConnectorCli({ packageJson, connector }) in the developer's package bin from @ken-jo/agent-connector/cli; comment that packageJson supplies identity while connector supplies behavior.
6. Foreground the developer's brand in MCP lifecycle/runtime commands: npx @acme/acme-db-mcp install, acme-db doctor --probe, acme-db upgrade, acme-db uninstall, acme-db telemetry report, etc.
7. Keep framework tooling separate: package emits host/MCP distribution artifacts, so document it as npx @ken-jo/agent-connector package --connector ... (or global agent-connector package for developers who installed the framework CLI).
8. Use other npx @ken-jo/agent-connector ... --connector commands only as a local framework development/debug fallback.
9. Verify with typecheck/tests, SDK offline harnesses when relevant, then doctor --probe when a real stdio server/host is available.

Hard Do-Nots

• Do not use agent-connector to write a brand-new MCP server protocol implementation. It deploys and measures an existing server command/URL.
• Do not present global @ken-jo/agent-connector install as the normal user install path for a branded MCP package.
• Do not claim connector-free usage can report per-MCP or per-tool cost.
• Do not duplicate package metadata in defineConnector unless there is a real override case.
• Do not patch host statusLine keys through configPatch; use the modeled statusline surface.
• Do not silently drop unsupported host surfaces; the expected behavior is native support, disabled, or skip-warn with a reason.
