Coolify MCP Server

Instructions

Implementation Reference

• src/tools/handlers.ts:391-393 (handler)

  The handler logic for the 'get_database' tool. It requires a 'uuid' parameter and fetches the database details from the Coolify API endpoint `/databases/{uuid}` using the CoolifyClient.

  case 'get_database':
    requireParam(args, 'uuid');
    return client.get(`/databases/${args.uuid}`);

• src/tools/definitions.ts:1063-1071 (schema)

  The schema definition for the 'get_database' tool, specifying the input parameters and description used for MCP tool registration and validation.

  {
    name: 'get_database',
    description: 'Get database details by UUID',
    inputSchema: {
      type: 'object',
      properties: { uuid: { type: 'string', description: 'Database UUID' } },
      required: ['uuid']
    }
  },

• src/index.ts:36-38 (registration)

  The MCP server registers all tools, including 'get_database', by providing the tool definitions from getToolDefinitions() in response to ListToolsRequest.

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

• src/index.ts:41-67 (registration)

  The MCP server handles tool calls by dispatching to handleTool, which routes 'get_database' to its specific case handler.

  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:30-30 (helper)

  'get_database' is listed as a read-only tool, ensuring it is available even in read-only mode.
