Walkthrough

The MCP crate now uses rmcp transports and session-bound workspace operations. The CLI supports asynchronous init, deinit, and serve --mcp commands. Documentation describes the new lifecycle and expanded tool set.

Changes

MCP session and CLI lifecycle

Layer / File(s)	Summary
rmcp transports and tool contracts crates/codegraph-mcp/Cargo.toml, crates/codegraph-mcp/src/http.rs, crates/codegraph-mcp/src/stdio.rs, crates/codegraph-mcp/src/tools.rs	The crate adds rmcp-based tool definitions and stdio serving. It adds a feature-gated HTTP transport stub.
Workspace session lifecycle crates/codegraph-mcp/src/session.rs, crates/codegraph-mcp/src/tools.rs, crates/codegraph-mcp/src/server-instructions.md	Sessions now bind, initialize, deinitialize, validate, reload, and reindex workspaces. Initialization can return extraction statistics.
Session-aware server dispatch crates/codegraph-mcp/src/lib.rs	CodegraphServer replaces the fixed-root server. Tool calls use session state and rmcp responses.
Reduced CLI and usage documentation crates/codegraph/src/main.rs, crates/codegraph/Cargo.toml, README.md	The CLI removes legacy commands and supports asynchronous lifecycle commands and MCP serving. README instructions reflect the new workflow and 30 tools.

Poem

I bound a workspace, said the rabbit with glee,
Then indexed its symbols beneath the MCP tree.
rmcp carried each call,
Sessions guarded them all,
And the CLI grew small as can be.
