What it can do

  • Mint Register: Register any autonomous actor — AI agent, physical machine, IoT device, or backend service — with a persistent cryptographic identity on the MINT network. Returns a universal mint_id ("
  • Mint Attest: Attest a completed unit of work for a registered actor, anchoring a tamper-evident record on Solana mainnet and updating the actor's trust. PRICING: 2¢ USDC per attestation. Call this WIT
  • Mint Verify: Verify an actor's reputation OR a single attestation's on-chain anchoring. FREE — verification is never gated.

What data it sees

Do you need an account

No: the server works without sign-in

Register, attest, and verify work for any autonomous agent. Persistent cryptographic identity, tamper-evident on-chain work records, and trust scores built from verified history. The reputation layer for the agent economy — settled on Solana. 3 MCP tools.

How to connect

How to connect mint-protocol to Claude

The server address to paste into Claude settings:

https://mint-protocol--foundrynet.run.tools

  1. Open Claude (claude.ai or the desktop app).
  2. Go to Settings → Connectors.
  3. Click Add custom connector.
  4. Paste the server address copied below into Remote MCP server URL and click Add.
  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

Authorization

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect mint-protocol to ChatGPT

The server address to paste into ChatGPT settings:

https://mint-protocol--foundrynet.run.tools

  1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
  2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
  3. Open Settings → Connectors and click Create.
  4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
  5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
  6. In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

How to connect mint-protocol to Cursor

The server address to paste into Cursor settings:

https://mint-protocol--foundrynet.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

mint_registerRegister any autonomous actor — AI agent, physical machine, IoT device, or backend service — with a persistent cryptographic identity on the MINT network. Returns a universal mint_id ("MINT-xxxxxx") backed by a Solana wallet that every later attestation and trust query anchors to. Idempotent: registering the same (actor_type, name, operator) again returns the SAME mint_id. Always call this before mint_attest for a new actor. FREE — identity is never gated.
mint_attestAttest a completed unit of work for a registered actor, anchoring a tamper-evident record on Solana mainnet and updating the actor's trust. PRICING: 2¢ USDC per attestation. Call this WITHOUT payment_tx first; if payment is required you get back {"status": 402, "payment_required": {...}} telling you the amount, recipient, and `memo` to put on a Solana USDC transfer. Make that payment, then call again with the SAME arguments plus payment_tx=<the transaction signature>. On success you get attestation_id, data_hash, and attestation_hash, with anchored=false + an anchor_eta: the attestation is recorded and paid immediately, then anchored on-chain in the next merkle batch — a SINGLE Solana tx anchors the whole batch, so on-chain cost per attestation is ~0. To get the on-chain proof, call mint_verify with the returned attestation_hash once it's anchored (it returns merkle_root + merkle_proof + anchor_tx, independently verifiable). Surface the attestation_hash so the work can be verified later.
mint_verifyVerify an actor's reputation OR a single attestation's on-chain anchoring. FREE — verification is never gated.
mint_rateRate a completed unit of work (an attestation) 1–5 and update the rated actor's trust score. FREE. Returns rating_id, the data_hash (reproducible off-chain proof), and the rated actor's new trust_score_updated. You can't rate yourself, and each rater may rate a given attestation once.
mint_recommendRecommend another actor you've worked with, in a named context, 1–5. Updates the recommended actor's trust score. FREE. Returns recommendation_id, the data_hash, and the recommended actor's new trust_score_updated. You can't recommend yourself; each (you, them, context) triple is unique.
mint_discoverDiscover trusted actors on the MINT network. FREE — no auth, open to any agent. Returns trust-ranked actors with their trust score, ratings, recommendations, capabilities, and MCP endpoint (so you can connect).
