​
Give agents current Handler docs

Handler’s documentation is available through a hosted MCP server at: 
https://handler.alduncanson.com/mcp
Connect an agent to this MCP endpoint when you want it to use Handler reliably instead of guessing command names or output shapes from model memory.

​
When this is useful

  • an AI coding assistant needs to call A2A agents from a shell
  • an internal agent should generate handler --output json ... commands
  • a workflow needs up-to-date examples for sessions, tasks, and server configuration
  • you want agents to discover Handler docs through MCP rather than a web browser
Give the agent a short, operational instruction like this: 
Use Handler to send A2A protocol messages, inspect agent cards, and manage A2A
tasks. Prefer structured output with `handler --output json` or
`handler --output ndjson` when another program or agent will consume the result.

​
Agent-friendly CLI pattern

For single responses, prefer JSON: 
handler --output json message send \
  --server production-agent \
  --text "Summarize the current task state"
For streaming responses, prefer newline-delimited JSON: 
handler --output ndjson message stream \
  --server production-agent \
  --text "Run the long workflow and stream progress"

​
Discover commands programmatically

Handler also exposes its own CLI shape for agents and automation: 
handler --output json schema

handler --output json describe message send

handler --output json describe task get
Use these commands when an agent needs to construct invocations dynamically. They are also useful for validating wrapper tools, command palettes, and generated documentation.

​
Built-in local agent behavior

The bundled local agent uses the same hosted docs MCP endpoint by default: 
handler server run agent
