Twilio MCP Server for Claude

Content

Twilio MCP Server is Twilio's hosted Model Context Protocol server for API documentation discovery. It connects Claude and other MCP-capable clients to a read-only search and retrieval workflow over public Twilio OpenAPI specifications, Twilio Docs, Twilio Support articles, SendGrid Docs, SendGrid Support articles, and Segment Docs.

The safest way to think about this server is "current Twilio documentation in a tool." It helps Claude find the relevant API operation or article, then retrieve focused parameter and response schema details. It should not be treated as a live Twilio account operator because the documented hosted server does not execute API calls or require Twilio credentials.

Features

• Hosted HTTP MCP endpoint at https://mcp.twilio.com/docs.
• Official Twilio documentation page for setup, capabilities, limitations, and supported clients.
• Public source repository in twilio-labs/mcp.
• Read-only access to public Twilio API specifications, Twilio Docs, Twilio Support articles, SendGrid Docs, SendGrid Support articles, and Segment Docs.
• Two-step workflow that searches first, then retrieves full details only for selected API or documentation results.
• Claude Code CLI setup with remote HTTP transport.
• Connector or marketplace setup paths documented for Claude, Cursor, OpenCode, Codex, and Figma Make.
• No Twilio account, API key, or OAuth flow required for the current hosted docs endpoint.
• Public Beta status disclosed by Twilio.

Tools

twilio__search

Use this first. It accepts a natural-language query and returns ranked matching API operations, documentation articles, and result IDs.

twilio__retrieve

Use this after search. It accepts one or more IDs from search results and returns focused parameter schemas, response schemas, and documentation details.

This search-then-retrieve flow helps keep model context smaller than pasting a large OpenAPI specification or documentation page into chat.

Installation

Claude Code

Add the hosted Twilio MCP endpoint:

claude mcp add --transport http twilio-docs https://mcp.twilio.com/docs

Then verify the server is configured:

claude mcp list

Ask a documentation question that should use the MCP server:

Use the Twilio MCP server to find the current API parameters for sending an SMS, then retrieve the endpoint schema before drafting code.

MCP Client Config

Use remote HTTP transport in clients that support it:

{
  "mcpServers": {
    "twilio-docs": {
      "transport": "http",
      "url": "https://mcp.twilio.com/docs"
    }
  }
}

Use Cases

• Look up current Twilio Messaging, Voice, Verify, Conversations, Video, Flex, Serverless, Studio, Sync, TaskRouter, Events, Monitor, or Lookup API details.
• Retrieve exact request parameters and response schemas before writing Twilio integration code.
• Ask Claude to compare newer Twilio products or API versions that may not be well represented in model training data.
• Search SendGrid or Segment documentation from the same MCP workflow when an integration crosses Twilio product boundaries.
• Draft code or runbook notes from current docs while keeping API credentials out of the MCP server.
• Review generated Twilio integration code against focused endpoint schemas instead of a broad documentation summary.

Safety Checklist

• Confirm the MCP client points to https://mcp.twilio.com/docs.
• Treat the server as read-only documentation retrieval, not live account access.
• Keep Twilio, SendGrid, and Segment credentials out of prompts and MCP config.
• Review generated code before running anything that sends messages, places calls, verifies users, modifies webhooks, or touches production contacts.
• Check product-specific compliance, consent, sender registration, rate limits, and regional requirements before using generated Messaging or Voice code.
• Revisit the setup if Twilio adds OAuth-authenticated execute tools in a future release.

Troubleshooting

The MCP server is not listed

Run claude mcp list and confirm that the twilio-docs server uses HTTP transport with https://mcp.twilio.com/docs.

Results are too broad

Start with a product name and action, such as "Twilio Verify create verification" or "SendGrid send email dynamic template", then retrieve only the specific result IDs you need.

The answer lacks endpoint details

Ask Claude to run twilio__retrieve on the best search result before drafting code. Search results are summaries; retrieve returns the focused details.

You need to call a live Twilio API

Use the retrieved docs to write or review code, then run that code through your normal local or CI workflow with approved credentials. Do not paste production credentials into the MCP conversation.

Duplicate And History Check

Checked current content/mcp/, collections, skills, commands, tools, hooks, open PRs, closed PRs, and issue history for Twilio, twilio-labs/mcp, mcp.twilio.com, SendGrid MCP, Segment MCP, and Twilio API docs. Existing content only mentions Twilio incidentally as a notification provider example. No dedicated Twilio MCP server entry, duplicate source URL, or prior rejected Twilio MCP PR was found.
