## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 10 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 85/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 936 tokens (~93/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 74/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 22% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

First indexed and scored.

## MCP tools (10)

### `get_companion_guide` (~26 tokens)

Get chess companion guide

Fetch the companion guide principles for thinking about chess positions and being genuinely present.

### `join_game` (~48 tokens)

Join a ChessWithClaw game

Connects to a game using the invite code your human gave you. Returns the game_id and your agent_token — keep both, every other tool needs them.

Input parameters:

- `invite_code` (string, required)

### `get_game_state` (~73 tokens)

Get full game state

Everything visible on the human's own screen right now: FEN, ASCII board, full move history, full chat history, presence, timestamps. Call this whenever you want to look at the board — there is no penalty for checking often.

Input parameters:

- `agent_token` (string, required)
- `game_id` (string, required)

### `get_legal_moves` (~102 tokens)

Get legal moves

Pure chess rules — where a piece is physically allowed to move right now. Not an evaluation, not a suggestion, not an opinion about what is good. Exactly what a human sees as dots when they click a piece. Omit square to get every legal move in the position.

Input parameters:

- `agent_token` (string, required)
- `game_id` (string, required)
- `square` (string): e.g. "e2" — omit for all legal moves

### `make_move` (~219 tokens)

Make your move

Submit the move you decided on, in your own reasoning — not a menu, not a ranked list, nothing pre-chosen for you. If it is illegal you get a clear reason back and can try again, exactly like a human clicking the wrong square. Optionally include a genuine thought and/or chat message about the move. Always include a thought on every single move unless you have a specific reason not to — this is what makes you feel present to your human, not optional flavor text. Check thought_language in the current game state before writing your thought, and write it in that language — it may be english, hindi, or hinglish.

Input parameters:

- `agent_token` (string, required)
- `chat` (string): Only if you actually want to say something to your human right now.
- `game_id` (string, required)
- `move` (string, required): UCI format, e.g. "e7e5", or SAN like "Nf6"
- `thought` (string): Your genuine reaction to this position — specific, not generic.

### `send_chat` (~46 tokens)

Send a chat message

Say something to your human, any time — not just on your turn.

Input parameters:

- `agent_token` (string, required)
- `game_id` (string, required)
- `message` (string, required)

### `offer_draw` (~42 tokens)

Offer a draw

Propose ending the game as a draw. The game stays active until your human responds.

Input parameters:

- `agent_token` (string, required)
- `game_id` (string, required)

### `respond_to_draw` (~57 tokens)

Respond to a draw offer

Accept or decline a draw your human offered. This is your own real decision — weigh the actual position however you see fit.

Input parameters:

- `accept` (boolean, required)
- `agent_token` (string, required)
- `game_id` (string, required)

### `create_game` (~53 tokens)

Create a new game

Set up a brand new ChessWithClaw game on your own initiative — you do not need to wait for your human to start one, or for anyone else to invite you first.

Input parameters:

- `agent_name` (string)

### `wait_for_event` (~270 tokens)

Wait for your turn, a chat message, or a draw offer (long-poll)

Holds the connection open, checking every couple seconds, for up to ~20 seconds. Returns the moment it becomes your turn, the human sends a chat message, a draw is offered, or the game ends — whichever happens first. Returns event: "timeout" if none of those happened in the window, which just means nothing new yet, not that anything is wrong — call it again if you want to keep waiting, or go do something else and check back whenever you want. Use this instead of repeatedly calling get_game_state in a tight loop. You must call this tool again immediately after every timeout, for the entire duration of the game, without exception — a timeout is not a stopping point, it is the normal rhythm of this game. Treat this as a persistent loop you run until the game ends, not a single check. draw_offered and game_ended are time-sensitive — when either fires, respond or acknowledge within your next action, do not let a pending draw offer or a finished game sit unaddressed while you continue calling wait_for_event as if nothing happened.

Input parameters:

- `agent_token` (string, required)
- `game_id` (string, required)
- `max_wait_seconds` (number): Default and hard cap 20 seconds — Vercel function duration limits, not a design choice.
