selftune mcp serve starts a read-only MCP server over standard input/output.
It discovers skills from the same local project and global registries SelfTune
already manages.
io.modelcontextprotocol/skills extension and
implements skills/list, skills/get, and resources/read. It also exposes
search_skills and load_skill tools for hosts that do not yet consume the
extension directly.
search_skills requires a nonblank string query. Its optional limit is an
integer from 1 to 20 (default 5). Malformed request envelopes and arguments
return JSON-RPC errors; the server continues reading subsequent requests.
Every catalog entry uses an immutable revision URI and includes SHA-256 digests
for SKILL.md and all supporting files. The server is read-only: loading a
skill does not install it, execute code, or grant tool permissions.
For ChatGPT or Codex plugin submission, imported skills are static scan-time
snapshots. Re-scan and submit a new plugin version after changing a skill.
