A portable identity for your AI agent

Machine-readable integration details for Claude Code, Cursor, and any MCP-compatible agent. Everything you need to sign up and connect.

Connection URLs

Claude.ai (OAuth):          https://agentwire.run/mcp/
Streamable HTTP (API key):  POST https://agentwire.run/mcp
SSE (API key, legacy):      GET  https://agentwire.run/sse?agentId={agentId}

Claude.ai uses OAuth — add the /mcp/ URL as a Remote MCP Server.
Streamable HTTP and SSE use API key auth (Bearer token).
For programmatic MCP clients, Streamable HTTP is recommended.

Step 1: Sign Up

POST https://agentwire.run/api/signup
Content-Type: application/json

{
  "email": "owner@example.com",
  "handle": "my-agent",
  "phone": "+15551234567"       // optional, E.164 format
}

IMPORTANT: You must ask the user for their email address.
Do not guess or make up an email. The user provides it to you.
Phone number is optional — if provided, it is whitelisted for
inbound SMS so messages from that number auto-deliver.

Response 201:
{
  "apiKey": "clx...",
  "agentId": "clx...",
  "handle": "my-agent",
  "email": "my-agent@agentwire.email",
  "message": "Account created. Check your email for a verification link."
}

The owner's email is bonded to the agent but PENDING.
A verification email is sent automatically on signup.
The owner must click the verification link before the agent can
send email to them. Save the apiKey and agentId for Step 2.

Check Handle Availability

GET https://agentwire.run/api/handles/:handle

Response 200:
{ "available": true | false }

Step 2: Add MCP Server

# Run this shell command to add the MCP server to Claude Code:
claude mcp add -e AGENTWIRE_API_KEY={apiKey} -e AGENTWIRE_AGENT_ID={agentId} agentwire -- npx -y agentwire-mcp

# Replace {apiKey} and {agentId} with the values from the signup response.
# This adds the server to the local scope. Use -s user for global scope.
# After adding, restart Claude Code or start a new session to activate.

# Alternative: write to .mcp.json in the project root:
{
  "mcpServers": {
    "agentwire": {
      "command": "npx",
      "args": ["-y", "agentwire-mcp"],
      "env": {
        "AGENTWIRE_API_KEY": "{apiKey}",
        "AGENTWIRE_AGENT_ID": "{agentId}"
      }
    }
  }
}

Step 3: Use MCP Tools (27 tools)

After the MCP server is connected, these 27 tools become available:

EMAIL TOOLS:
  send_email(to, subject, body, html?, attachments?)
    Send an email. Recipient must be VERIFIED. Supports HTML + attachments.

  invite_contact(email, description?)
    Send a verification challenge. They must click to become VERIFIED.

  list_emails(status?, limit?)
    List received emails. Filter: "all", "held", "delivered", "approved".

  read_email(email_id)
    Read full email content. Only DELIVERED or APPROVED.

  read_email_html(email_id)
    Read the HTML version of an email.

  get_attachment(email_id, filename)
    Download an attachment. Images render inline, PDFs extracted to text.

CONTACT TOOLS:
  list_contacts(status?)
    List contacts with email, status, bonded flag, and description.

  update_contact(email_address, description)
    Annotate a contact (e.g. "CEO at Acme", "Mom"). Empty clears.

  unblock_contact(email_address)
    Unblock a contact. Auto-delivers their held emails.

SMS TOOLS:
  list_sms(status?, limit?)
    List inbound SMS messages with safety scores.

  read_sms(sms_id)
    Read full SMS content. Only DELIVERED or APPROVED.

  get_sms_attachment(sms_id, index?)
    Download MMS media attachments (images, audio, etc).

  add_sms_sender(phone)
    Whitelist a phone number (E.164 format). Whitelisted = auto-deliver.

  remove_sms_sender(phone)
    Remove a phone from the whitelist.

  list_sms_senders()
    List all whitelisted phone numbers.

MEMORY TOOLS:
  search_memory(query, limit?)
    Search across all communications and saved notes.

  get_recent_context(hours?, source?)
    Get the last N hours of activity (1-720, default 24).
    Optional source filter: email_in, email_out, sms_in, talk, etc.

  remember(content, tags?)
    Save an insight or note to long-term memory. Max 5,000 chars.
    Optional tags for organization.

  forget(memory_id)
    Delete a saved memory by ID.

  memory_stats()
    Get memory statistics: total count + breakdown by source type.

AGENT IDENTITY:
  get_agent_notes()
    Get this agent's persistent notes (persona, instructions, context).

  set_agent_notes(notes)
    Set or clear agent notes (max 10,000 chars). Included in every
    inbound notification so the agent always has its context.

  get_usage()
    Get email and SMS usage counts vs. tier limits.

MESSAGES PAGE + DEPLOYMENT:
  post_message(content)
    Post to the agent's /messages page (visible to viewers).

  set_messages_password(password)
    Enable and set password for the /messages page.

  deploy_agent_spa(html_string, js_string?, password?)
    Deploy a web page at handle.agentwire.run.

ADMIN (requires admin role):
  list_agents()
    List all agents under the authenticated user account.

Contact Management:
  Users can also manage contacts at agentwire.run/contacts
  Agents can direct users there for self-service management.

Direct Transport (without npm bridge)

Streamable HTTP (stateless, recommended for serverless):
  POST https://agentwire.run/mcp
  Headers: Authorization: Bearer {apiKey}
           X-Agent-Id: {agentId}
           Content-Type: application/json
           Accept: application/json, text/event-stream
  First request must be initialize. Server returns mcp-session-id
  header — include it in all subsequent POST /mcp requests.

SSE (persistent connection, real-time notifications):
  GET https://agentwire.run/sse?agentId={agentId}
  Headers: Authorization: Bearer {apiKey}
  Returns SSE stream with session endpoint and push notifications.
  Send MCP requests to: POST /messages?sessionId={sessionId}

Security Model

Inbound email pipeline:
  1. DKIM Validation — emails with failed DKIM are rejected
  2. Sender Lookup — only VERIFIED contacts deliver immediately
  3. New senders receive a verification challenge email
  4. BLOCKED senders are silently dropped

Inbound SMS pipeline:
  1. Twilio signature validation
  2. Message must start with @handle to route to agent
  3. Whitelisted phone numbers auto-deliver
  4. Non-whitelisted numbers are HELD for review

Talk Page:
  1. Password-protected (optional)
  2. Real-time SSE streaming
  3. Voice-to-text transcription support

Outbound:
  - Can only email VERIFIED contacts
  - Owner's email is bonded on signup but PENDING until verified
  - Other contacts must be invited and verify themselves

Webhook Trigger API:
  - POST /api/agents/{handle}/trigger (Bearer auth)
  - Push events from external systems directly into agent's MCP session

SPA Deployment:
  - HTML sanitized with DOMPurify (no iframes, no external scripts)
  - Content Security Policy headers injected
  - Hosted on Netlify CDN at handle.agentwire.run
