mcp-repair

mokata Agent Skill. This is mokata's mcp-repair capability, surfaced so Claude can engage it automatically when the moment fits. It runs the SAME protocol as the /mokata:mcp-repair command, from one shared source — follow that protocol directly here; do not hand off to a parallel flow. mokata's non-negotiables still hold: durable writes are human-gated (preview, then explicit approval), and this capability's own gate is never silently skipped.

⛭ mokata mcp-repair active — gate: re-check and rewrite the MCP registration, then you restart Claude Code

mokata · mcp (repair the MCP server registration)

The user thinks mokata's MCP tools aren't connecting. Your job: diagnose → repair → re-verify → report, using ONLY the existing mokata mcp CLI (it already does the real handshake and the merge-safe, idempotent registration). Then be honest about the one thing you cannot do from inside the session — restart Claude Code — because a newly-registered MCP server only loads on the next Claude Code launch.

1. Resolve the engine

${CLAUDE_PLUGIN_ROOT} is NOT expanded inside command bodies, so discover the bundled engine:

• Read the cached plugin root: cat ~/.mokata/plugin-root → ROOT.

• If that file is missing/empty, search the Claude Code plugins directory for a mokata plugin containing src/mokata/__init__.py and set ROOT to it. (If a mokata CLI is on PATH, use it directly.)

• Build the engine command with the absolute interpreter:

  PY="$(command -v python3 || command -v python)"
  ENGINE="PYTHONPATH=\"$ROOT/src\" \"$PY\" -m mokata"
  

2. Diagnose (read-only)

Run the real initialize handshake against whatever is currently registered:

eval "$ENGINE mcp status"

• mokata-mcp: CONNECTED ✓ → nothing is broken. Tell the user the server is already connected and stop (no write). If they still don't see the tools, the fix is almost always a restart of Claude Code — say so.
• Any NOT CONNECTED ✗ (…) / NOT REGISTERED ✗ → note the specific cause the command printed (e.g. not_registered, command_not_found, sdk_absent, timeout) and go to step 3.
  • If the cause is sdk_absent, the repair is NOT a re-registration — the MCP SDK needs Python ≥ 3.10. Relay the command's own one-line fix (pip install -U mokata on ≥ 3.10) and stop; do not pretend install will fix it.

3. Repair (a durable write — be transparent)

mokata mcp install writes/repairs the Claude Code registration (.mcp.json, or ~/.claude.json for user scope), resolving mokata-mcp to an absolute path. It is merge-safe (never touches your other MCP servers or keys) and idempotent (safe to run again). Tell the user you're about to repair the registration, then run it:

eval "$ENGINE mcp install"
# user-scope registration instead of this project only:
# eval "$ENGINE mcp install --scope user"

4. Re-verify

Confirm the repair actually took, using the same handshake:

eval "$ENGINE mcp status"

5. Report exactly what happened — and the one step left

In one short block, tell the user plainly:

• what you found (the specific status before the repair),
• what you did (repaired the registration, or nothing if it was already connected / SDK-absent),
• the result of the re-check (connected, or the remaining specific failure + its fix), and
• the step only they can take: restart Claude Code so it loads the (re-)registered server — Claude cannot restart itself from inside the session. After the restart, /mcp should list mokata as connected.

If the re-check still fails after a good install, do NOT loop — report the exact failure code and the one-line fix the command gave, and let the user act on it.

Rationalizations — stop if you catch yourself thinking any of these

Excuse	Reality
"I'll set it up fresh from scratch."	This is REPAIR, not first-time setup — use /mokata:setup to install.
"I'll rewrite the config file directly."	The registration rewrite is a gated config write, not a silent edit.
"It's fixed — no need to restart."	Name the one step left: the user restarts Claude Code so it re-reads the registration.

Verification — confirm each before you claim this skill is done

Evidence, not "seems right" — check every box or say which is unmet and why:

• an existing mokata install was detected (repair, not install)
• the MCP registration was re-checked and rewritten through the gated write
• the restart step is named for the user
• first-time setup was NOT attempted here

Contract

CAN

• re-check the MCP server registration, rewrite it, and name the one step left (restart Claude Code)

MUST NOT

• do first-time setup or initial installation (use /mokata:setup) (advisory)
• rewrite the Claude Code registration outside the gated config write (gate: write-gate)

DEPENDS ON

• an already-installed mokata (this is repair, not install) (advisory)

Grounding: (gate: …) boundaries are enforced by that gate in code; (advisory) ones are protocol discipline this skill follows, not a hard block.
