You need a Sign and register statements on a Forestrie log key (create it on the maker’s site) · 3 setting(s) to fill in (MCP_REGISTER_PAY_MAX_PER_CALL, MCP_REGISTER_PAY_MAX_PER_DAY, MCP_REGISTER_PAY_ASSET) · Install Node.js on your computer first (one time) · Only the Claude desktop app (Windows or Mac), not the web or phone

Let AI install it

Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server Sign and register statements on a Forestrie log for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "register": { "command": "npx", "args": [ "-y", "@forestrie/mcp-register" ], "env": { "FORESTRIE_GRANT": "your-value", "FORESTRIE_AUTHORITY_GRANT": "your-value", "FORESTRIE_KNOWN_SEALER_KEY": "your-value", "MCP_REGISTER_PAY_MAX_PER_CALL": "your-value", "MCP_REGISTER_PAY_MAX_PER_DAY": "your-value", "MCP_REGISTER_PAY_ASSET": "your-value" } } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) For FORESTRIE_GRANT, FORESTRIE_AUTHORITY_GRANT, FORESTRIE_KNOWN_SEALER_KEY, MCP_REGISTER_PAY_MAX_PER_CALL, MCP_REGISTER_PAY_MAX_PER_DAY, MCP_REGISTER_PAY_ASSET, leave "your-value" in place and tell me to paste the real value myself into the file or the app’s field. Never ask me to type a key in chat. 5) Do what we agreed, then check that the Sign and register statements on a Forestrie log tools really show up.

Common questions

Is Sign and register statements on a Forestrie log safe?

It passed 3 of 3 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: FORESTRIE_GRANT, FORESTRIE_AUTHORITY_GRANT, FORESTRIE_KNOWN_SEALER_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 13 days ago, and the latest version (0.3.0) reached the registry 13 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?

@forestrie/mcp-register

An MCP server that signs a statement and registers it on a Forestrie transparency log under a Forestrie-Grant, then waits for the seal and verifies the receipt. It can also buy the grant: as the requester, it signs a child grant under your own authority log and registers it with canopy, paying canopy's x402 charge within hard caps. It is the write path of the Forestrie MCP trio:

The statement is signed with a log key the server holds. The default backend for that key is an ES256 key file the server creates. Child grants are signed with a separate authority key, held the same way. The model never handles signature bytes: you pass the payload and the server signs it. No tool takes a signature or a key as input.

Paying is optional, and the payer is yours. The server never creates a payer key and holds no funds of its own: you choose how payment happens (see Choosing a payer). Whichever you choose, a payer key never crosses the MCP boundary, and the spending caps are configuration, not tool arguments. With no payer configured, the server spends nothing: it returns canopy's payment requirements, and you pay from your own x402 wallet (relay mode).

Status

Version 0.1.1 on npm, published with provenance from publish.yml. 0.1.0 was published by hand and has no provenance attestation; use 0.1.1 or later.

Tools

ToolWhat it does
get_log_keyReturns the log key's public half (x‖y). Your grant must name this key. The key is created on first use.
delegate_sealingAuthorises the operator's sealer for your data log. Runs canopy's prepare with the same grant first if the coordinator does not know the log's public root yet. Once per log.
register_statementSigns a payload (inline base64 or a file path, up to 4 MiB, with an explicit content type) and registers it.
check_registrationDoes one status check: pending, awaiting_seal or sealed. Once sealed, it saves the receipt.
verify_registrationVerifies the receipt over the statement with mcp-verify's verifier and returns its four answers unaltered.
issue_grantAs the requester, signs a child data-log grant with the authority key, naming a log key (by default this server's), sized with maxHeight. Sends nothing.
register_grantRegisters the child grant with canopy, pays its 402 within the caps or relays the requirements, and follows it to its receipt. Resumable by child log id; never pays twice.

The prompts walk an agent through the work:

  • `register` covers the key and the grant, sealing, registering, waiting, verifying and keeping the receipt.
  • `audit` explains which trust questions a receipt answers under which trust root.
  • `issue-and-pay` covers buying a grant as the requester: sizing it, issuing it, paying within the caps or relaying the payment, and handing the completed grant to the performer.

Configuration

Every value can be overridden per call.

FORESTRIE_ROOT_LOG_IDthe forest's root log id (R in /register/{R}/entries)

MCP_REGISTER_AUTHORITY_KEY_FILEthe authority key file, default $MCP_REGISTER_HOME/authority-key.jwk
Choosing a payer

Whoever wants the work done pays for it: the requester, paying canopy directly. The server supports three ways to do that and prefers none of them.

SetupWhat you configureWho holds the key
Relaynothingyour own x402 wallet: register_grant returns canopy's payment requirements and resumes on a call that carries your X-PAYMENT
Key fileMCP_REGISTER_PAYER_KEY_FILE and the caps belowa file on the machine that runs the server
Your own backendcreateServer({ payer }) from @forestrie/mcp-register/server, when you embed the serverwhatever your PayerBackend uses: a hosted wallet, a KMS, a remote signer

A backend of your own must sign an EIP-3009 authorisation with the nonce it is given. That nonce is what stops one grant being paid for twice (see Payment settings).

Example: a dedicated key file

This is one way to set up the key-file payer, not the way. Any EVM account works; what matters is that it pays for this and nothing else.

  1. Create a private key in a file only you can read. Any wallet tool that exports a raw private key will do. With no extra tools:
   ( umask 077; printf '0x%s\n' "$(openssl rand -hex 32)" > payer.key )

The server accepts one line, 0x and 64 hex digits, in a regular file (not a symlink) that no other user can read.

  1. Find the account's address with a tool you already trust to derive one from a private key, or by importing the key into a wallet you use.
  1. Fund the address with the asset canopy charges in. On the default network, Base Sepolia, that is testnet USDC, from Circle's faucet. The account needs no ETH: it only signs an authorisation, and the x402 facilitator submits the transfer and pays its gas.
  1. Point the server at the file and set the caps:
   MCP_REGISTER_PAYER_KEY_FILE=/path/to/payer.key

MCP_REGISTER_PAY_MAX_PER_CALL=100000 # $0.10 MCP_REGISTER_PAY_MAX_PER_DAY=1000000 # $1.00

Keep one account per requester. Payments settle on chain, so anyone can link a payer address to the grants it paid for. To rotate the key, create a new one, move what is left to it, and point MCP_REGISTER_PAYER_KEY_FILE at the new file.

Payment settings

These are read from the environment only. No tool argument can set or raise them.

VariableMeaning
MCP_REGISTER_PAYER_KEY_FILEan EVM private key (0x + 64 hex, mode 600) that pays; unset means relay mode
MCP_REGISTER_PAY_MAX_PER_CALLthe most one payment may be, in the asset's atomic units (required with a payer)
MCP_REGISTER_PAY_MAX_PER_DAYthe most all payments in one UTC day may total (required with a payer)
MCP_REGISTER_PAY_NETWORKthe one network it pays on, default eip155:84532 (Base Sepolia)
MCP_REGISTER_PAY_ASSETthe one asset it pays in, default USDC on Base Sepolia
MCP_REGISTER_PAY_TOoptional: the only payee
MCP_REGISTER_PAY_ALLOW_MAINNET1 to pay on a network that is not a testnet; off by default

The server pays only the canopy named in FORESTRIE_BASE_URL, and only for the request it made. Every payment it signs for a grant uses a nonce derived from that grant, so the token contract can settle at most one of them: a retry or two overlapping calls never pay for one grant twice. Each signed payment is written to the spend ledger before it is sent and counts toward the daily cap whether or not it settles. The daily cap is approximate when calls overlap. USDC has 6 decimals, so 10000 is $0.01.

Where grants come from

Forestrie runs no grant issuer. Whoever owns the authority log above yours issues your grant, naming the key that get_log_key returns. Canopy sequences grants; it does not issue them.

That owner can be you. If the owner of the root above you creates an authority log for your authority key (get_log_key with which: "authority" returns it as a PEM for forestrie-cli's create-log --auth-log --signer-pem), issue_grant and register_grant let you issue and register your own child grants. If that authority log carries the child-payment-required flag, each registration is paid for over x402, straight to the transparency operator.
