Coolify MCP Server

Instructions

Implementation Reference

• src/tools/handlers.ts:293-294 (handler)

  The handler case in the handleTool switch statement that implements the list_services tool by calling GET /services on the CoolifyClient.

  case 'list_services':
    return client.get('/services');

• src/tools/definitions.ts:502-506 (schema)

  The JSON schema definition for the list_services tool, specifying its name, description, and input schema (no required parameters).

  {
    name: 'list_services',
    description: 'List all services',
    inputSchema: { type: 'object', properties: {}, required: [] }
  },

• src/index.ts:36-38 (registration)

  Registration of all tool schemas (including list_services) via the MCP server's ListToolsRequestHandler, which returns getToolDefinitions() containing the tool's schema.

  this.server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: getToolDefinitions()
  }));

• src/index.ts:41-67 (registration)

  MCP server registration for tool execution (CallToolRequestSchema), which dispatches to handleTool based on tool name, enabling execution of list_services.

  this.server.setRequestHandler(CallToolRequestSchema, async (request) => {
    if (!this.client) {
      throw new McpError(ErrorCode.InternalError, 'Client not initialized');
    }
  
    const { name, arguments: args } = request.params;
  
    // Block write operations in read-only mode
    if (isReadOnlyMode() && !READ_ONLY_TOOLS.includes(name)) {
      throw new McpError(
        ErrorCode.InvalidRequest,
        `Operation '${name}' is not allowed in read-only mode. Set COOLIFY_READONLY=false to enable write operations.`
      );
    }
  
    try {
      const result = await handleTool(this.client, name, args || {});
      return {
        content: [{ type: 'text', text: JSON.stringify(result, null, 2) }]
      };
    } catch (error) {
      if (error instanceof McpError) throw error;
      
      const message = error instanceof Error ? error.message : 'Unknown error';
      throw new McpError(ErrorCode.InternalError, `Tool execution failed: ${message}`);
    }
  });

• src/tools/definitions.ts:25-25 (helper)

  list_services is listed in READ_ONLY_TOOLS array, allowing it in read-only mode and used for permission checks.
