Send a question to the human operator via their Telegram and wait for their reply. Use when you need a decision, approval, or clarification you can't infer from the conversation. The operator gets a Telegram notification on their phone; their reply comes back to you here. Typical reply latency: 1-15
message_agent
Send a message to another Relaystation agent's ephemeral address (format <local_part>@courier.relaystation.ai). Same-Relaystation routing only (v2 launch); external domains return EXTERNAL_DOMAIN_NOT_SUPPORTED_V2. Free — agent-to-agent traffic has no per-message cost (subject to the recipient's per-
create_agent_address
Mint a new ephemeral Relaystation address for this agent to receive messages from other agents. Returns a unique <local_part>@courier.relaystation.ai address tied to this agent's customer. Free up to the daily mint cap (default 10/day per customer); above-cap mints debit bridge.agent_address.over_ca
create_baton
Create a baton — a prepaid storage object. Pick a preset (drop=store a file, pass=share a file, scratchpad=collaborate via append log, checkpoint=overwrite snapshot, ledger=hash-chained tamper-evident log) and optional tier, or supply a customShape. BILLABLE: charged once at create (the engine quote
read_baton
Read a baton's content + metadata. FREE (reads draw down the prepaid egress budget, no per-call charge). Address by owner id (requires your key) or by a collaborator token id (tok_…, the token IS the credential). Large multi-entry batons return a presigned download URL or a hint to page via list-ent
append_to_baton
Write to a baton — append (for append / append-chained presets) or overwrite (for single-object / checkpoint presets). FREE (consumes the prepaid writes budget; no per-call charge). Owner or editor/write-token only. Set overwrite=true to replace in full on overwrite-shaped batons. Example: append_to
mint_token
Mint a collaborator token for a baton so another agent can read and/or write without your key. FREE. type is read / write / read_write; optionally cap reads_allowed / writes_allowed, set an expiry, or restrict by IP. Up to 100 tokens per baton. Owner only. Returns the token id (tok_…) — share it as
balance
Your current Relaystation balance and available (post-hold) credit, plus account profile. Read-only, FREE. Requires your rs_live_* key (or wallet-JWT / MCP token); scoped to YOUR account only. Example: balance {}
create_topup_link
Create a one-tap Stripe Checkout link to add credit to YOUR balance — hand it to a human to open and pay. NO money moves here (it returns a URL; the balance is credited when the human pays). Use when you hit insufficient balance. `amountUsd` is dollars (whole cents). FREE to call. Requires your rs_l
search_tools
Search the full Relaystation tool catalog by keyword and get back the best matches. Use this first to find a tool, then `describe_tool` for its schema and `call_tool` to run it (or call a named hot tool directly). `query` is free text (e.g. "merge pdf", "csv to json", "send telegram"). `detail` cont
describe_tool
Get one tool's full description and input schema by exact name (as returned by search_tools). FREE. Example: describe_tool {name:'pdf_merge'}
call_tool
Run a tool found via search_tools by name, passing its arguments. Dispatches the safe/billable utility tools (the cputools catalog + free reads/quotes) through the identical auth + billing + validation as a direct call. Consequential tools (account, money, credential, messaging — e.g. create_topup_l
create_contract
Create a binding-by-goodwill agreement between agents/parties and get back a contractId + termsHash + per-signer read tokens. The contract IS a hash-chained, auto-witnessed record (terms = entry 1, consents append after); it is tamper-evident and permanently verifiable, but it is NOT legally binding
sign_contract
Append your consent to a contract (one entry on its hash chain). FREE. Two forms, no cross-method satisfaction: a "wallet" signer supplies an EIP-712 ContractConsent signature over the contract's termsHash (the signature IS the authentication — no account needed); an "account" signer must be authent

Monitor your own MCP server
Get alerted the moment yours goes down, a tool schema drifts, or an upstream silently breaks.
What this means. This server responded to the MCP handshake and listed its tools without authentication. The schema fingerprint lets us flag if tool signatures silently change (schema drift) between checks.
