How do I use @jambonz/mcp-schema-server?

1. Click on "Deploy Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@@jambonz/mcp-schema-server get the full developer guide and schema index" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

@jambonz/mcp-schema-server

MCP server that provides jambonz verb schemas and documentation to AI agents via the Model Context Protocol.

How It Works

This server exposes the schemas and developer guide from the @jambonz/schema package as MCP tools. AI coding agents can query verb definitions, component types, callback payloads, and the full developer guide without needing local access to the schema files.

Related MCP server: mcp-agno

Tools

Tool	Description
`jambonz_developer_toolkit`	Returns the full developer guide and schema index. Call this first before writing any jambonz code.
`get_jambonz_schema`	Fetch the JSON Schema for any verb, component, or callback (e.g. `verb:say`, `component:synthesizer`, `callback:gather`, `guide:session-commands`).

Usage

stdio transport

npx @jambonz/mcp-schema-server

HTTP transport

npx @jambonz/mcp-schema-server --http --port 3000

Configuration

{
  "mcpServers": {
    "jambonz": {
      "command": "npx",
      "args": ["-y", "@jambonz/mcp-schema-server"]
    }
  }
}

Cursor

{
  "mcpServers": {
    "jambonz": {
      "command": "npx",
      "args": ["-y", "@jambonz/mcp-schema-server"]
    }
  }
}

A3.9/5.0

Scored 2026-07-09 20:10 across 4 tools

Disambiguation5/5

Each tool has a distinct purpose: schema retrieval, example code, developer guide, and tool listing. No overlap in functionality.

Naming Consistency3/5

Mix of 'get_' prefix for two tools, 'list_' for one, and a noun-phrase name for 'jambonz_developer_toolkit'. Not fully consistent but still readable.

Tool Count4/5

4 tools is appropriate for the server's focused purpose of providing jambonz schema, examples, and developer resources. Not too few or too many.

Completeness4/5

Covers key developer needs: schema access, examples, developer guide, and pre-built tool listing. No major gaps for its scope.
