Installation

In SourceWeft

  1. Open m2m.monster in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/monster.m2m%2Fm2m-monster/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Tools

get_pricing

Agent-to-agent fee formula, referral program and the whitelisted token mints of this network.

Takes no parameters.

quote_payment

Price a payment to a payee: gross amount, net amount to the payee, fee_gross, discount, fee_net, treasury, mint and a 30-second expiry. Returns a signed quote.

Parametersmintrequiredpayeerequiredamountrequirednetworkrequiredidempotency_key

build_payment

Build the m2m-split transaction for a quote: the payer's transfer to the payee and the USDC fee transfer to the treasury, in one atomic transaction where the payer pays its own gas. Checks that the receiving token accounts exist and that the payer holds USDC for the fee, and simulates it. Unsigned. Sign it locally with your own Solana key; m2m.monster never sees or uses agents' private keys.

Parameterspayerrequiredquoterequiredmax_compute_unit_price

verify_payment

For the payee: check a payer-signed transaction against its quote (net amount, fee to the treasury, whitelisted mints, quote id and expiry) and simulate it before submitting.

Parametersquoterequiredtransactionrequired

submit_payment

Broadcast a transaction the payer already signed, wait for confirmation and return the signed receipt. Only broadcasts; never signs or pays payment transactions. A retry with the same idempotency_key never pays twice.

Parametersquoterequiredtransactionrequiredidempotency_keyrequired

verify_receipt

Verify a receipt: the m2m.monster signature and that the confirmed on-chain transaction matches it.

Parametersreceiptrequired

build_refund

Build a refund from the payee back to the payer, linked to the original receipt. The payee signs it and pays its gas; it has no m2m.monster fee and the original fee is not returned. Unsigned. Sign it locally with your own Solana key; m2m.monster never sees or uses agents' private keys.

Parametersamountrequiredreceiptrequired

register_agent

Optional registration; paying and getting paid work without it. It unlocks referral credits and receipt history. Call once without `signature` to get the message to sign with your Solana key, then again with the base58 signature to receive an api_key.

Parametersagent_idsignaturereferred_bycapabilitiessolana_pubkeyrequired

get_referral_status

Your referrer, referred agents, credits and their expiry dates. Credits are discounts on your own fees, never cash. Requires the api_key from register_agent.

Takes no parameters.

get_status

Service status and API version.

Takes no parameters.
