Implementation Reference

• src/catalog.js:316-330 (schema)

  The tool 'get_pre_brief' is defined in the catalog.js, which acts as the static definition for MCP tools. It specifies the tool name, description, and input schema.

  {
    name: 'get_pre_brief',
    description: 'Writes your pre-call prep so you don\'t walk in cold — talk track, discovery questions tuned to this buyer, anticipated objections, and the one thing you need to get done in this meeting. Just say who you\'re meeting with — Andru checks your calendar automatically.',
    annotations: READ_ONLY,
    inputSchema: {
      type: 'object',
      properties: {
        companyName: {
          type: 'string',
          description: 'Company you\'re meeting with. Andru finds the matching calendar event and pulls attendee context automatically.',
        },
        contactName: {
          type: 'string',
          description: 'Name of the person you\'re meeting (optional — helps match the right event and personalize the brief).',
        },

• src/server.js:47-68 (handler)

  The actual execution of 'get_pre_brief' happens by proxying the request to an external backend service through the `client.callTool` method. The server doesn't contain the implementation logic itself, but handles the routing of the tool execution call.

  server.setRequestHandler(
    CallToolRequestSchema,
    async (request) => {
      if (!client) {
        return {
          content: [{ type: 'text', text: JSON.stringify({ error: 'ANDRU_API_KEY not configured. Tool execution requires an API key.' }) }],
          isError: true,
        };
      }
      const { name, arguments: args } = request.params;
      try {
        return await client.callTool(name, args || {});
      } catch (error) {
        return {
          content: [{
            type: 'text',
            text: JSON.stringify({ error: error.message }),
          }],
          isError: true,
        };
      }
    }

• src/client.js:36-38 (helper)

  The `AndruClient` class in `client.js` is responsible for sending the tool execution request to the remote Andru API backend, where the business logic for 'get_pre_brief' is implemented.

  async callTool(name, args) {
    return this.post('/api/mcp/tools/call', { tool: name, arguments: args });
  }
