jdx mcp

IDE equivalent: MCP stdio server (typed jdx_* tools)

Serve the MCP stdio server: each jdx query as a typed jdx_* tool with a generated schema, for agents that speak Model Context Protocol. Holds the workspace in memory for the session, so repeated queries are instant. MCP clients spawn this as a child process and talk JSON-RPC over stdin/stdout.

Usage#

jdx mcp [<options>]

Options#

Option	Description
`-w, --workspace=<text>`	Stored workspace the server answers from (default: default). A missing workspace reads as an error naming the fix; individual tool calls may override it per call.
`-h, --help`	Show this message and exit
