Parfii-bot da4d88910a chore(workspace): SSoT inheritance + version unification Group E — Cargo workspace hygiene (post-audit 2026-05-02). Workspace dependency inheritance: - 40+ member crates migrated from inline dep pinning to { workspace = true }. Was: every crate redeclared clap/serde/rusqlite/tokio/etc inline, defeating the [workspace.dependencies] SSoT and forcing N edits per upgrade. Authoritative pins now live solely in _primitives/_rust/Cargo.toml. Major version splits resolved: - dashmap: 5 vs 6 (kei-cortex/kei-gateway) -> 6 in workspace - tower: 0.4 vs 0.5 (kei-cortex/kei-forge) -> 0.5 in workspace - notify: 6 vs 8 (kei-projects-watcher/kei-watch+kei-skills) -> 8 in workspace - thiserror: 1 vs 2 (workspace/keisei) -> kept 1; keisei downgraded Closed: dual-major compilation = wasted build time + ABI mismatch risk at trait boundaries. Profile / orphan cleanup: - kei-changelog/Cargo.toml: deleted [profile.release] block (workspace member profiles are silently ignored by Cargo since 1.0). - kei-brain-view/Cargo.toml: removed dangling "[workspace] table stripped on merge" comment (orphan from prior decomposition). rust-version SSoT: - 27+ member crates migrated from inline rust-version = "1.75" to rust-version.workspace = true. Workspace declares 1.77; the inline 1.75 pins were stale and misleading (with resolver 2 the workspace MSRV won anyway). cargo check --workspace: clean (only pre-existing sqlx-postgres future-incompat warning + frustration-matrix dead-code warning, neither introduced by this change). Note: _assembler/ lives outside _primitives/_rust workspace, so its Cargo.toml was not touched here. Remaining edition-2024 question for _assembler is a separate decision.

kei-mcp — Model Context Protocol server

kei-mcp exposes the KeiSeiKit atom registry over the Model Context Protocol so MCP-aware clients (Claude Code, Cline, OpenClaw, etc.) can discover and call our 13 atoms + N primitives as MCP tools, and read our skills as MCP resources.

What you get

Tools — every atom in _primitives/_rust/*/atoms/*.md becomes one MCP tool. Tool name is the atom's full id (<crate>::<verb>), the description is the first paragraph of the atom's body, and the input schema is the JSON-Schema referenced by the atom's frontmatter.
Resources — every skills/<name>/SKILL.md becomes one MCP resource at skill://<name> returning the SKILL.md text on read.
Prompts — placeholder list (empty) for now.

Wire format

JSON-RPC 2.0 over stdio, line-delimited (one request per line, one response per line). stdout carries protocol frames ONLY; everything else (diagnostics, warnings) goes to stderr.

Supported methods: initialize, tools/list, tools/call, resources/list, resources/read, prompts/list, prompts/get.

Build

cargo build -p kei-mcp --release
# binary: target/release/kei-mcp

Configuration (env)

Variable	Default	What it does
`KEI_MCP_ATOMS_ROOT`	`_primitives/_rust`	Where to walk for `<crate>/atoms/*.md`
`KEI_MCP_SKILLS_ROOT`	`skills`	Where to walk for `<name>/SKILL.md`
`KEI_RUNTIME_BIN_DIR`	(unset)	Resolve `<crate>` binaries here before falling back to `$PATH`

Register with Claude Code

Add to ~/.claude/mcp_servers.json:

{
  "kei": {
    "command": "/absolute/path/to/kei-mcp",
    "args": [],
    "env": {
      "KEI_MCP_ATOMS_ROOT": "/absolute/path/to/KeiSeiKit/_primitives/_rust",
      "KEI_MCP_SKILLS_ROOT": "/absolute/path/to/KeiSeiKit/skills",
      "KEI_RUNTIME_BIN_DIR": "/absolute/path/to/KeiSeiKit/_primitives/_rust/target/release"
    }
  }
}

Register with Cline

Edit Cline's cline_mcp_settings.json (open via Cline: Edit MCP Settings from the command palette):

{
  "mcpServers": {
    "kei": {
      "command": "/absolute/path/to/kei-mcp",
      "args": [],
      "env": {
        "KEI_MCP_ATOMS_ROOT": "/absolute/path/to/KeiSeiKit/_primitives/_rust",
        "KEI_MCP_SKILLS_ROOT": "/absolute/path/to/KeiSeiKit/skills"
      }
    }
  }
}

Register with OpenClaw

Add to ~/.openclaw/mcp.json:

{
  "servers": {
    "kei": {
      "command": "/absolute/path/to/kei-mcp",
      "args": [],
      "env": {
        "KEI_MCP_ATOMS_ROOT": "/absolute/path/to/KeiSeiKit/_primitives/_rust",
        "KEI_MCP_SKILLS_ROOT": "/absolute/path/to/KeiSeiKit/skills"
      }
    }
  }
}

Manual smoke test

echo '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05"}}' \
  | ./kei-mcp

You should see one line of JSON on stdout containing serverInfo.name: "kei-mcp".
