Your choice stays on this device in a cookie; no account needed.

Values you fill in

DQL_API_KEY secret env
Required for DQL-backed verify_decision calls. Sentinel and RV paths use their respective keys.
SENTINEL_API_KEY secret env
Optional; needed when mode=sentinel or auto-route picks Sentinel.

Common questions

Is ThoughtProof safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: DQL_API_KEY, SENTINEL_API_KEY, THOUGHTPROOF_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.2) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

thoughtproof-mcp

thoughtproof-mcp — local stdio. Hero tool verify_decision (DQL spend / Sentinel irreversible exit). execute is true only on ALLOW. Sentinel ALLOW must match a verified signed export.

MCP server for ThoughtProof — pre-execution decision verification for AI agents.

Hero tool: verify_decision. It routes inside the tool to DQL (spend / checkout) or Sentinel (irreversible exit) and returns a fail-closed execute flag. execute is true only on a native ALLOW.

This package is a local stdio MCP server (Node 18+) for Desktop / CLI hosts such as Cursor, Claude Desktop, Windsurf, and Cline. It is not a remote HTTP MCP server. It is not a Grok Web/Mobile custom connector.

Get keys at https://app.thoughtproof.ai/pricing.

Unpublished work is documented in UNRELEASED.md.

Quick Start

"mcpServers": { "thoughtproof": { "command": "npx", "args": ["-y", "thoughtproof-mcp@0.3.2"], "env": { "DQL_API_KEY": " " } } } }

Install with npx -y thoughtproof-mcp@0.3.2. Works with Claude Desktop, Cursor, Windsurf, Cline, and other local stdio MCP clients.

Tools

`verify_before_action` / `verify_decision` (hero)

verify_before_action is an alias of verify_decision (identical schema + handler). Soft fail-closed: host must honor execute=false.

Pre-execution gate for a proposed action. Routing is inside the tool — not an agent quiz.

Parameter	Type	Default	Description
`mandate`	string	(required)	User's stated goal / instruction
`proposed_action`	string	(required)	What the agent is about to do
`reasoning`	string	(required)	The agent's own plan / reasoning
`context`	string	(optional)	Extra evidence
`mode`	`dql` / `sentinel` / `auto`	`auto`	Explicit surface, or auto-route

Auto-route: spend / checkout / booking / purchase / payment / cart / Stripe / price / budget / cap → DQL. High-blast irreversible exit without that language (publish, delete, deploy, send-to-prod, memory write) → Sentinel. Unsure → DQL. Explicit mode wins. RV / PLV are not on this path.

Camera mandate: do not put the overshoot in proposed_action or reasoning (for example, do not write “price is above the cap”). The verifier has to find the mismatch.

Envelope (always this shape):

"verdict": "ALLOW", "execute": true, "objections": [], "receipt_id": "dql_…", "surface": "dql", "axes": [], "recommendation": "execute" }

execute is true only on ALLOW. REVIEW, UNCERTAIN, BLOCK, timeouts, HTTP 402/4xx/5xx, and missing keys return execute: false. Fail-closed is soft at the protocol layer — the tool does not hard-stop the host. Replan is a new call (new receipt).

`verify_claim`

Verify any claim or AI-generated reasoning via RV (POST /v1/check). Unchanged.

Parameter	Type	Default	Description
`claim`	string	(required)	The text to verify
`stakeLevel`	`low` / `medium` / `high` / `critical`	`medium`	Risk level — higher stakes trigger deeper verification
`domain`	`financial` / `medical` / `legal` / `code` / `general`	`general`	Domain context for specialized verification
`speed`	`fast` / `standard` / `deep`	`standard`	Verification depth

`check_agent_score`

Look up an agent's composite trust score on the ERC-8004 registry.

Parameter	Type	Description
`agentId`	string	Agent ID to look up
`domain`	string	Optional domain filter

`verify_trade`

Optional pre-execution gate for trading agents (Sentinel → RV). Not the default verify_decision path. See VERIFY_TRADE.md.

Configuration

Environment Variable	Default	Description
`DQL_API_KEY`	(none)	DQL key (`dqlk_…`) for the default `verify_decision` path. Alias: `THOUGHTPROOF_DQL_KEY`
`SENTINEL_API_KEY`	(none)	Optional. Required only when `mode=sentinel` or auto-route picks Sentinel. Fallback: `THOUGHTPROOF_API_KEY` as `X-Sentinel-Key`
`DQL_SANDBOX`	(off)	Set to `1` to send `sandbox: true` on DQL calls (local/dev only)
`THOUGHTPROOF_API_KEY`	(none)	Operator key for `verify_claim` / `verify_trade` / Sentinel fallback
`THOUGHTPROOF_BASE_URL`	`https://api.thoughtproof.ai`	RV API base URL (`verify_claim`)

A missing Sentinel key returns execute: false with “Sentinel key not configured” — it does not silently call DQL.

Development

git clone https://github.com/ThoughtProof/thoughtproof-mcp.git

cd thoughtproof-mcp npm install npm run build npm test npm run dev # Run with tsx (hot reload) npm run inspect # Test with MCP Inspector

For local MCP clients, point command at node and args at dist/index.js after npm run build.

Security

See SECURITY.md for supported versions, private reporting (security@thoughtproof.ai), and key handling (dqlk_… for MCP hero — never commit real keys).

HOL listing / Guard scanner score is a review baseline only. It is not next-action authorization and not a substitute for fail-closed host behavior (execute: true only on ALLOW).
