Coolify MCP Server

Instructions

Implementation Reference

• src/tools/handlers.ts:45-46 (handler)

  Handler implementation for the 'get_version' tool. Simply calls the CoolifyClient's GET method on the '/version' endpoint.

  case 'get_version':
    return client.get('/version');

• src/tools/definitions.ts:113-116 (schema)

  Schema definition for the 'get_version' tool, including name, description, and empty input schema (no parameters required).

    name: 'get_version',
    description: 'Get Coolify version information',
    inputSchema: { type: 'object', properties: {}, required: [] }
  },

• src/index.ts:41-67 (registration)

  MCP server registration for tool calls (CallToolRequestSchema). Dispatches to handleTool based on tool name, with read-only mode checks.

  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/index.ts:36-38 (registration)

  MCP server registration for listing tools (ListToolsRequestSchema). Returns all tool definitions including 'get_version'.

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

• src/tools/definitions.ts:5-6 (helper)

  'get_version' is listed in READ_ONLY_TOOLS array, ensuring it's always available even in read-only mode.

  'get_version',
  'health_check',
