mcp-node-server
A remote MCP server that exposes machine resources like filesystem, terminal, camera, and input to AI agents over HTTP, enabling access from anywhere on the network.

DISPLAYWAYLAND_DISPLAYTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
32/32 tools missing one or more hints — audio_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); audio_capture (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); audio_play (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +29 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Destructive tools are labelled
7 tools perform destructive updates without destructiveHint — audio_capture deletes at line 609 (os.unlink(output_path)); audio_play deletes at line 722 (os.unlink(output_path)); camera_capture deletes at line 451 (os.unlink(output_path))
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
Descriptions match behaviour
2 tools describe read intent but their handlers mutate — audio_list (line 311: result = subprocess.run(); camera_list (line 270: result = subprocess.run()
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
27/32 tool handlers declare input schemas (84%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
24/32 tool handlers wrap calls in try/catch (75%)
Wrap each tool handler body in try/catch and return a structured error response.
Tests exist
No test files found
Add tests that exercise each declared tool.
No access to sensitive paths
Reads sensitive paths: ~/.config/mcp-node-server/config.yaml, ~/.config/mcp-node-server/config.yaml, ~/.config/mcp-node-server/config.yaml
Remove reads of sensitive system paths. If you genuinely need them, document why in the README.
Tool description accuracy
3 tools have description/behavior mismatches: audio_list: description implies read-only but handler writes/deletes/executes; camera_list: description implies read-only but handler writes/deletes/executes; screen_capture: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
