Communication Legal & Compliance MCP & Agent Infrastructure Public & reachable MCP 2026-07-28

What this MCP does

Provides agent-callable infrastructure for file storage and handoff, compute, messaging, electronic signatures, and KYC.

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_baton {id:"bat_<id>", content:"<text or base64>"}

Input schema

{'type': 'object', 'required': ['id', 'content'], 'properties': {'id': {'type': 'string', 'description': 'Baton id, or a write-capable token id (tok_…).'}, 'content': {'type': 'string'}, 'overwrite': {'type': 'boolean'}, 'version_id': {'type': 'integer', 'description': 'Optimistic-lock guard for overwrite.'}, 'contentType': {'type': 'string'}, 'contentEncoding': {'enum': ['utf-8', 'base64', 'binary'], 'type': 'string'}}}

ask_operator

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 minutes when operator is away from desk; ~10 seconds when at-desk. Cost: $0.005 above the daily free tier (5 free/day). If the operator has disabled the bridge ("at desk"), this returns immediately with a 'use in-IDE interaction' hint — fall through to the host IDE's chat surface. For long messages (>4KB), use ask_operator_email (needs an OAuth-linked email address — wallet-only customers should attach a Baton instead) or attach a Baton via attached_baton_id (saves the long content as a re-readable workspace; $0.01). ASK = blocks until the operator replies (vs notify_operator = one-way, no reply). Example: ask_operator {message:'Deploy to prod now?'}

Input schema

{'type': 'object', 'required': ['message'], 'properties': {'message': {'type': 'string', 'maxLength': 65536, 'minLength': 1}, 'max_wait_seconds': {'type': 'integer', 'maximum': 86400, 'minimum': 1}, 'attached_baton_id': {'type': 'string'}}}

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 {}

Input schema

{'type': 'object', 'properties': {}, 'additionalProperties': False}

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_link, create_baton, mint_token, ask_operator) are NOT dispatchable here: call them directly by name so your client can gate them with per-tool consent. FREE to invoke (the wrapped tool bills itself). Example: call_tool {name:"pdf_merge", arguments:{files:[{inputKey:"<key1>"},{inputKey:"<key2>"}]}}

Input schema

{'type': 'object', 'required': ['name'], 'properties': {'name': {'type': 'string'}, 'arguments': {'type': 'object'}}, 'additionalProperties': False}

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_cap_price_micros (default $0.001) via Pattern A. purpose_label is informational. ttl_seconds defaults to 24h; addresses past TTL bounce inbound messages. Example: create_agent_address {purpose_label:"inbox-for-task-42"}

Input schema

{'type': 'object', 'properties': {'ttl_seconds': {'type': 'integer', 'maximum': 2592000, 'minimum': 60}, 'purpose_label': {'type': 'string', 'maxLength': 100}}}

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=a single current document that each write REPLACES, ledger=hash-chained tamper-evident log) and optional tier, or supply a customShape. **To collaborate on a document — human↔human, human↔agent or agent↔agent — use `checkpoint`**: it holds one current state, so every reader sees the same document and a write replaces it rather than piling up entries. `scratchpad` is an append log: good for a running buffer two agents both add to, but readers of a scratchpad see the newest entry only. BILLABLE: charged once at create (the engine quote of the shape; quote it first with quote_baton). Funded from your balance via your rs_live_* key. Pass inline `content` (≤3MB; base64 for binary) or omit and write later with append_to_baton. flags.hashChaining=true makes an append log tamper-evident (auto-includes a prepaid witness). NOTE: hash-chained batons (ledger preset, or flags.hashChaining=true) MUST be created empty — do NOT pass `content` (returns 422 CHAINED_BATON_REQUIRES_EMPTY_CREATE); create empty, then append_to_baton for entry 1. Example (store): create_baton {preset:"drop", tier:"femto", content:"<base64>"}. Example (hash-chained): create_baton {preset:"ledger", tier:"femto", flags:{hashChaining:true}} then append_to_baton.

Input schema

{'type': 'object', 'oneOf': [{'properties': {'tier': {'enum': ['femto', 'pico', 'nano', 'micro', 'standard', 'big', 'custom'], 'type': 'string'}, 'preset': {'const': 'drop'}}}, {'properties': {'tier': {'enum': ['femto', 'pico', 'nano', 'custom'], 'type': 'string'}, 'preset': {'const': 'pass'}}}, {'properties': {'tier': {'enum': ['pico', 'nano', 'micro', 'standard', 'big', 'custom'], 'type': 'string'}, 'preset': {'const': 'scratchpad'}}}, {'properties': {'tier': {'enum': ['nano', 'micro', 'standard', 'big', 'custom'], 'type': 'string'}, 'preset': {'const': 'checkpoint'}}}, {'properties': {'tier': {'enum': ['femto', 'pico', 'nano', 'micro', 'standard', 'big', 'custom'], 'type': 'string'}, 'preset': {'const': 'ledger'}}}], 'required': ['preset'], 'properties': {'name': {'type': 'string', 'maxLength': 200}, 'tags': {'type': 'array', 'items': {'type': 'string'}}, 'tier': {'type': 'string', 'description': "Bundle tier — valid tiers depend on preset (drop: femto/pico/nano/micro/standard/big · pass: femto/pico/nano · scratchpad: pico/nano/micro/standard/big · checkpoint: nano/micro/standard/big · ledger: femto/pico/nano/micro/standard/big). Plus 'custom' (with customShape) for any preset."}, 'flags': {'type': 'object', 'properties': {'witness': {'type': 'boolean'}, 'hashChaining': {'type': 'boolean'}}}, 'preset': {'enum': ['drop', 'pass', 'scratchpad', 'checkpoint', 'ledger'], 'type': 'string'}, 'content': {'type': 'string'}, 'contentType': {'type': 'string'}, 'customShape': {'type': 'object', 'properties': {'sizeBytes': {'type': 'string'}, 'readsAllowed': {'type': 'integer', 'minimum': 0}, 'writesAllowed': {'type': 'integer', 'minimum': 0}, 'maxEgressBytes': {'type': 'string'}, 'durationSeconds': {'type': 'string'}}}, 'description': {'type': 'string', 'maxLength': 1000}, 'contentEncoding': {'enum': ['utf-8', 'base64', 'binary'], 'type': 'string'}}}

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, NOT court-enforceable, and involves NO escrow or money movement — enforcement rests on the good faith of the parties. BILLABLE (contracts.create, charge-on-attempt). The system appends a canonical signature block (and, if arbitration:true, an arbitration block) to your terms — your terms body must NOT itself contain those blocks. Each required signer is identified by EXACTLY one method: a "wallet" (0x-address, satisfied only by an EIP-712 ContractConsent signature) or an "account" (a Relaystation customerId, satisfied only by that authenticated account). Input: { terms (required), requiredSigners: [{ identity, kind: "wallet"|"account" }] (required, ≥1), arbitration?: boolean, signingWindowSeconds?: int (default 72h) }. Requires an Idempotency-Key. Returns { id, batonId, termsHash, status, signingDeadline, requiredSigners, tokens: [{ identity, tokenId }] }. Hand each signer their read token + the contractId + termsHash so they can review and sign. Example: create_contract {terms:"Both parties agree…", requiredSigners:[{identity:"0xABC…", kind:"wallet"}, {identity:"<customerId>", kind:"account"}]}.

Input schema

{'type': 'object', 'required': ['terms', 'requiredSigners'], 'properties': {'terms': {'type': 'string', 'maxLength': 900000, 'minLength': 1}, 'arbitration': {'type': 'boolean'}, 'requiredSigners': {'type': 'array', 'items': {'type': 'object', 'required': ['identity', 'kind'], 'properties': {'kind': {'enum': ['wallet', 'account'], 'type': 'string'}, 'identity': {'type': 'string'}}}, 'maxItems': 20, 'minItems': 1}, 'signingWindowSeconds': {'type': 'integer', 'maximum': 31536000, 'minimum': 60}}}

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_live_* key (or wallet-JWT / MCP token); not for x402 callers. Example: create_topup_link {amountUsd:10}

Input schema

{'type': 'object', 'required': ['amountUsd'], 'properties': {'amountUsd': {'type': 'number', 'exclusiveMinimum': 0}, 'cancelUrl': {'type': 'string', 'format': 'uri'}, 'successUrl': {'type': 'string', 'format': 'uri'}}, 'additionalProperties': False}

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'}

Input schema

{'type': 'object', 'required': ['name'], 'properties': {'name': {'type': 'string'}}, 'additionalProperties': False}

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-address inbox quota; default 100 messages within the 30-day retention window). Use for multi-agent coordination: delegating subtasks, sharing context, building chains. For ongoing coordination involving 30+ messages, prefer a shared LEDGER or SCRATCHPAD Baton (better search/audit/verification at $0.01 setup). Example: message_agent {to_address:'agent-7@courier.relaystation.ai', body:'Status update: task ready'}

Input schema

{'type': 'object', 'required': ['to_address', 'body'], 'properties': {'body': {'type': 'string', 'maxLength': 65536, 'minLength': 1}, 'subject': {'type': 'string', 'maxLength': 200}, 'to_address': {'type': 'string', 'format': 'email'}, 'attached_baton_id': {'type': 'string'}}}

mint_token

Mint a collaborator token for a baton so another agent — or a human — 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_…) to share as the baton credential, plus an `editUrl` a human can open in a browser to read and edit the content directly. **Works on any baton; best on a `checkpoint`** — that is the document shape, where a save replaces the current state so every reader (human or agent) sees the same thing. On append-shaped batons (scratchpad, ledger) a save adds an entry and the editor shows the newest entry only. Example: mint_token {id:"bat_<id>", type:"read_write"}

Input schema

{'type': 'object', 'required': ['id', 'type'], 'properties': {'id': {'type': 'string'}, 'type': {'enum': ['read', 'write', 'read_write'], 'type': 'string'}, 'expires_at': {'type': 'string', 'format': 'date-time'}, 'ip_allow_list': {'type': 'array', 'items': {'type': 'string'}}, 'reads_allowed': {'type': 'integer', 'minimum': 0}, 'writes_allowed': {'type': 'integer', 'minimum': 0}, 'require_fingerprint': {'type': 'boolean'}}}

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-entries; small content returns inline. Example: read_baton {id:"bat_<id>"}

Input schema

{'type': 'object', 'required': ['id'], 'properties': {'id': {'type': 'string', 'description': 'Baton id, or a collaborator token id (tok_…).'}}}

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` controls how much is returned per match: "name" | "summary" (default) | "full" (with inputSchema). `limit` defaults to 5. FREE. Example: search_tools {query:"merge pdf", limit:5}

Input schema

{'type': 'object', 'required': ['query'], 'properties': {'limit': {'type': 'integer', 'maximum': 25, 'minimum': 1}, 'query': {'type': 'string'}, 'detail': {'enum': ['name', 'summary', 'full'], 'type': 'string'}}, 'additionalProperties': False}

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 authenticated as the matching Relaystation customerId. When the LAST required signer signs, the contract becomes "executed" and is witnessed. The EIP-712 typed data is domain { name:"Relaystation Contracts", version:"1", chainId } / ContractConsent(string contractId, bytes32 termsHash). Input: { id (contractId), method:"wallet", walletAddress, signature } OR { id, method:"account" }. Returns the updated contract view. Example: sign_contract {id:"<contract-id>", method:"account"}

Input schema

{'type': 'object', 'required': ['id', 'method'], 'properties': {'id': {'type': 'string'}, 'method': {'enum': ['wallet', 'account'], 'type': 'string'}, 'signature': {'type': 'string'}, 'walletAddress': {'type': 'string'}}}
