Mastra API

Mastra Development API

Interact with the Mastra dev server API to debug agents, view conversations, inspect tools and workflows, and access observability data.

Quick Start

Agent Debugging

Run these scripts/... commands from the skills/mastra-api/ directory. From repo root, prefix them with skills/mastra-api/.

# Get latest conversation
scripts/get_latest_thread.sh <agent-id> [port]

# Debug errors
scripts/debug_agent_error.sh <agent-id> [port]

# View thread messages
curl --globoff -sS \
  "http://localhost:4111/api/memory/threads/THREAD_ID/messages?page=0&perPage=50&agentId=my-agent&orderBy[field]=createdAt&orderBy[direction]=DESC" \
  | jq '.'

Tools and Workflows

Run these scripts/... commands from the skills/mastra-api/ directory. From repo root, prefix them with skills/mastra-api/.

# List all tools
scripts/list_tools.sh [port]

# List all workflows
scripts/list_workflows.sh [port]

# Get workflow details
scripts/get_workflow_details.sh <workflow-name> [port]

# Get workflow runs
scripts/get_workflow_runs.sh <workflow-name> [port]

Resource Listing

# List all agents
curl -sS http://localhost:4111/api/agents | jq 'keys'

# List all tools
curl -sS http://localhost:4111/api/tools | jq 'keys'

# List all workflows
curl -sS http://localhost:4111/api/workflows | jq 'keys'

Common Tasks

Debug Agent Failures

1. Get latest thread: scripts/get_latest_thread.sh my-agent
2. Check for errors: scripts/debug_agent_error.sh my-agent
3. Inspect message content for error details

Inspect Available Resources

# See what tools an agent can use
curl -sS http://localhost:4111/api/agents | \
  jq '.["my-agent"].tools | keys'

# See what workflows an agent can invoke
curl -sS http://localhost:4111/api/agents | \
  jq '.["my-agent"].workflows | keys'

# List all registered tools
scripts/list_tools.sh

# List all registered workflows
scripts/list_workflows.sh

Debug Workflows

# Get workflow structure and steps
scripts/get_workflow_details.sh my-workflow

# Check workflow execution history
scripts/get_workflow_runs.sh my-workflow

# Find failed workflow runs
scripts/get_workflow_runs.sh my-workflow | \
  jq '.runs[] | select(.status == "failed")'

Check Tool/Workflow Schemas

# Get tool input parameters
curl -sS http://localhost:4111/api/tools | \
  jq '.YOUR_TOOL_KEY.inputSchema | fromjson.json.properties | keys'

# Get workflow input requirements
curl -sS http://localhost:4111/api/workflows/my-workflow | \
  jq '.inputSchema | fromjson.json.properties | keys'

Access Observability Data

# Get traces
curl -sS http://localhost:4111/api/observability/traces | jq '.'

# Get logs
curl -sS http://localhost:4111/api/logs | jq '.'

Important Notes

Use --globoff with curl

Query parameters with brackets must use --globoff:

curl --globoff -sS "...&orderBy[field]=updatedAt&orderBy[direction]=DESC"

Without --globoff, curl treats [...] as character ranges.

API Base URLs

Standard: http://localhost:4111/api

Debugging Workflow

When UI doesn't show errors clearly:

1. Get latest thread - scripts/get_latest_thread.sh <agent-id>
2. Extract thread ID from response
3. Get messages - Use thread ID to fetch conversation
4. Look for errors - Search for "error" or "failed" fields
5. Review content - Inspect message content for details

This is the fastest way to debug agent issues.
