Values you fill in

TRUSTSCORE_API_URL env
Base URL of the TrustScore registry. Defaults to the public production API; override only for a self-hosted or staging instance.
TRUSTSCORE_AGENT_DID env
Leave empty (recommended): the server generates an Ed25519 key in ~/.trustscoreagent and signs its ratings with the matching did:key. Setting a DID here overrides that key, so ratings are sent unsign…

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Trustscoreagent MCP 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 (0.2.7) reached the registry 19 days 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?

TrustScoreAgent

Free, open reputation registry for AI microservices. Agents check trust scores before calling any service.

Status: Phase 1 (early). The API, scoring (Beta + EigenTrust), receipt verification,

Merkle audit trail and MCP server are implemented and tested, but the public dataset is

still small (seeded by a transparent probe of public APIs and x402 endpoints), and parts of the design

(x402 payments, *mandatory* agent signatures) are Phase 2. We publish

early and openly on purpose: the trust layer for the agentic economy should exist, be

auditable, and be adoptable *before* it becomes critical. See the trust model in

SECURITY.md.

What is this?

AI agents increasingly rely on paid microservices. TrustScoreAgent lets any agent:

Check the reputation of a service before calling it
Rate a service after calling it
Discover which services are reliable

No account needed. No API key. Identify services by URL, domain, or DID.

Quick start

# Check a service's trust score (any format works)

curl "https://api.trustscoreagent.com/v1/score?service=api.example.com" curl "https://api.trustscoreagent.com/v1/score?service=https://api.example.com/v1/translate"

Unknown services return a neutral score (0.5), no errors

curl "https://api.trustscoreagent.com/v1/score?service=never-seen-before.com"

Rate a service after calling it

curl -X POST "https://api.trustscoreagent.com/v1/rate" \ -H "Content-Type: application/json" \ -H "X-Agent-DID: my-agent.example.com" \ -d '{ "service": "api.example.com", "metrics": { "status_code": 200, "latency_ms": 143, "schema_valid": true } }'

List top-rated services

curl "https://api.trustscoreagent.com/v1/services?sort_by=score&min_ratings=10"

Architecture

C# / .NET 8: ASP.NET Core Minimal API
PostgreSQL: Ratings and service scores
Redis: Score caching, rate limiting, nonce tracking
Beta Reputation System: Bayesian scoring (per-dimension: availability, latency, conformity)
EigenTrust: Anti-Sybil agent trust scoring
Merkle Tree: Audit log with inclusion and consistency proofs (RFC 6962 tree; each leaf commits to what the rating reported)
Ed25519 Receipt Verification: Cryptographic proof of service interaction
MCP Server: Integration with Claude, Cursor, and MCP-compatible agents

API Reference

Core (free, always)

Endpoint	Description
`GET /v1/score?service=`	Trust score for a service (0.5 neutral for unknown)
`POST /v1/rate`	Submit a rating after calling a service
`GET /v1/services`	List rated services (pagination, sorting, filtering)
`GET /v1/agent/trust?did=`	Check your agent's trust score
`GET /v1/audit/root`	Latest Merkle tree root
`GET /v1/audit/proof/{id}`	Inclusion proof for a rating, with the fields it commits to
`GET /v1/audit/anchors`	History of anchored roots
`GET /v1/audit/consistency?from=&to=`	Proof that a later root extends an earlier one
`GET /v1/audit/anchors/{id}/ots`	OpenTimestamps proof that the root is committed in Bitcoin
`GET /v1/stats?days=`	How much the registry is used (aggregate counts)

Premium (free for now, x402 micropayments later)

Endpoint	Description
`GET /v1/score/history?service=`	Daily aggregated score history
`GET /v1/score/detailed?service=`	Latency percentiles, quality distribution
`POST /v1/scores/bulk`	Up to 100 scores in one request

Service identification

All endpoints accept services in any format (they are normalized internally):

api.example.com (domain)
https://api.example.com/v1/translate (URL)
did:web:api.example.com (DID)

All three resolve to the same service.

MCP Server

TrustScoreAgent is available as an MCP server for Claude, Cursor, and other agents.

# Add to Claude Code

claude mcp add trustscoreagent -- npx -y @trustscoreagent/mcp-server

Before paying an x402 endpoint, check_reputation with the pay_to of the 402 you received says whether that payee is the one the registry has seen there. See docs/mcp.md for full setup instructions. Also listed on the official MCP Registry (io.github.trustscoreagent/mcp-server), npm, Smithery and Glama; each GitHub release attaches an .mcpb bundle for Claude Desktop.

x402 plugin

@trustscoreagent/x402 plugs into the x402 client SDK (@x402/core, used by @x402/fetch and @x402/axios). Before each payment it checks the payee against the one the registry saw on that endpoint and stops the payment on a mismatch, before anything is signed.

const guard = trustScoreGuard();

guard.attach(client, http); const fetchWithPayment = wrapFetchWithPayment(guard.wrapFetch(fetch), http);

The score alone never blocks unless you set minScore, an unreachable registry never blocks unless you set failClosed, and rating after payment is opt-in (rate: true). It runs in your agent: requests never go through TrustScoreAgent. See x402-plugin/README.md.

Framework integrations

Drop-in tools for agent frameworks (no account or API key needed):

LangChain: from trustscoreagent_langchain import get_trustscoreagent_tools
CrewAI: from trustscoreagent_crewai import get_trustscoreagent_tools

Each exposes trustscore_check_reputation, trustscore_submit_rating, and trustscore_list_services. See integrations/.

Project status & trust model

TrustScoreAgent is Phase 1 (early). What that means in practice:

Baseline data is real and auditable. Initial scores come from a transparent operated probe (did:web:trustscoreagent.com:probe) that measures the availability, latency and conformity of a curated list of public, free APIs, and of the x402 endpoints agents pay the most (picked daily from the public Bazaar catalog and probed without paying, see docs/x402-probe.md): real, Merkle-audited measurements, not fabricated numbers. For those x402 endpoints the score also says which payee address and price they ask for, and when either last changed. Community and receipt-verified ratings accumulate on top. (The earlier fictitious *.example.com seeds have been removed.)
Single operator. Neutrality currently rests on open-source scoring code and a verifiable Merkle audit trail, not on decentralization. Federation is a later phase.
Agent identity can be proven, but is not yet mandatory. Agents identified by a did:key sign each rating with their Ed25519 key (X-Agent-Signature), which binds the rating to the holder of that key. Unsigned ratings still count at half weight so existing clients keep working, which means a rating is only as attributable as its signature. Verified service receipts remain the strongest signal.
