Connecting Claude and ChatGPT to the AsteriskRecipes MCP Server

AsteriskRecipes.com runs a public, read-only MCP (Model Context Protocol) server at https://asteriskrecipes.com/mcp. It gives AI assistants direct, structured access to the site's reference library, applications, functions, AGI commands, AMI actions and events, and module configuration, instead of relying on whatever the model picked up during training (which is often outdated or wrong for a specific Asterisk version).

No API key, no account, no sign-up. It's rate-limited but otherwise open to anyone.

Connecting Claude and ChatGPT to the AsteriskRecipes MCP Server

What it's for

Ask your assistant something like "what arguments does the Asterisk Dial() application take" or "which AMI events fire during a transfer," and instead of guessing, it can query this server for the current, correct answer sourced directly from the Asterisk project's own XML documentation.

This is a good fit for:

Writing or debugging dialplan and needing accurate application/function signatures
Checking whether an application or AMI action is available in a specific Asterisk version
AGI/AMI development where argument order and event fields matter
Any workflow where you're already using an AI assistant alongside Asterisk work

Connecting Claude Code

Claude Code can add a remote HTTP MCP server directly from the command line:

claude mcp add --transport http asteriskrecipes https://asteriskrecipes.com/mcp --scope user

--scope user makes the server available in every project on your machine, not just the one you're currently in. Verify the connection:

/mcp

You should see asteriskrecipes listed as connected.

If you'd rather hand-edit config instead of using the CLI, add this to ~/.claude.json (user scope) or your project's .mcp.json:

{
  "mcpServers": {
    "asteriskrecipes": {
      "type": "http",
      "url": "https://asteriskrecipes.com/mcp"
    }
  }
}

Connecting Claude Desktop or claude.ai

Custom remote connectors work the same way across claude.ai, Claude Desktop, and Cowork, since they all connect through Anthropic's cloud rather than your local machine.

Go to Settings > Connectors
Click Add custom connector
Enter the server URL: https://asteriskrecipes.com/mcp
Click Add. No OAuth client ID or secret is needed, this server has no authentication.

To use it in a conversation, click the + button in the chat input, choose Connectors, and toggle it on.

Team and Enterprise plans

An Owner has to add the connector at the organization level first (Organization settings > Connectors > Add > Custom > Web), after which individual members connect it themselves under Customize > Connectors.

Connecting ChatGPT

ChatGPT supports custom MCP connectors through Developer Mode (Pro, Team, Enterprise, and Edu plans):

Settings > Connectors > Advanced, toggle Developer mode on
In a chat, open the connectors menu and add a custom connector
Enter the server URL: https://asteriskrecipes.com/mcp

The server implements the search and fetch tool contract ChatGPT's connector UI requires, so it works without any extra configuration.

Available tools

Tool	What it does
`search_reference`	Search the reference library by keyword. Returns matching entry titles, IDs, and short descriptions.
`get_reference_entry`	Fetch the full markdown content of one entry by category and slug.
`list_reference_categories`	List reference categories (applications, functions, AGI commands, AMI actions, AMI events, module configuration) with entry counts.
`compatibility_lookup`	List entries available as of a given Asterisk version, useful for checking whether something exists on an older install.
`search` / `fetch`	Fixed single-argument contract required by ChatGPT and similar connector UIs. Equivalent to `search_reference` and `get_reference_entry` under the hood.

Example prompts

Once connected, you don't need to name the tools directly, just ask:

"Look up the Asterisk ConfBridge application and summarize its arguments."
"What AMI events does a blind transfer generate?"
"Is the PJSIP_DIAL_CONTACTS function available in Asterisk 16?"
"List every AGI command related to call recording."

Scope and limits

This server is intentionally narrow:

Read-only. No tool can create, edit, or delete anything. It queries the same published content the site renders publicly, nothing more.
Reference section only. Snippets, scripts, and guides aren't exposed through this server (v1). Browse those on the site directly.
Rate-limited. Fair-use limits apply per client, same as the rest of the site.
No authentication required, none offered. There's nothing behind this server worth protecting with a login; it's the same content search engines already index.

Discovery for AI agents and crawlers

Agents that support machine-readable discovery don't need this guide at all. The server publishes:

An MCP Server Card (draft SEP-2127) at /mcp/server-card, linked from every page's <head> via <link rel="mcp-server-card">
A domain-wide MCP catalog at /.well-known/mcp/catalog.json
A mention in llms.txt alongside the rest of the site's AI-facing metadata
