mcp_server_scan.py DOX

Purpose

• Own the mcp_server_scan.py API endpoint.
• Provide static and optional runtime inspection for a single MCP server draft before it is added to global or project MCP config.
• Keep this file-level DOX profile synchronized with mcp_server_scan.py because this directory is intentionally flat.

Ownership

• mcp_server_scan.py owns the runtime implementation.
• mcp_server_scan.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Classes:
• McpServerScan (ApiHandler)
  • async process(self, input: dict[Any, Any], request: Request) -> dict[Any, Any] | Response

Runtime Contracts

• HTTP handlers must derive from helpers.api.ApiHandler; WebSocket handlers must derive from helpers.ws.WsHandler.
• The request accepts a server draft object, inspect_runtime, allow_remote_network, and allow_local_execution.
• Remote runtime inspection may contact the configured MCP URL to list tools only when allow_remote_network is true and static checks have no errors.
• Local stdio runtime inspection must not execute unless allow_local_execution is true.
• Response data redacts headers and env values.
• Update this file whenever request payloads, authentication or CSRF requirements, response shapes, route side effects, or WebSocket event contracts change.
• Imported dependency areas include: asyncio, helpers.api, helpers.mcp_handler, shutil, typing, urllib.parse.

Key Concepts

• Static checks report invalid URLs, non-HTTPS remote URLs, missing local commands, interpreter-style local commands, headers/env presence, and obvious prompt-injection markers in inspected tool descriptions.
• Static errors skip runtime inspection; remote network inspection and local command execution both require explicit trust flags.
• Runtime inspection creates a temporary MCPConfig in a worker thread so stdio/remote tool listing does not call asyncio.run() inside the request event loop.

Work Guidance

• Preserve authentication, CSRF, loopback, and API-key checks unless the endpoint contract explicitly changes.
• Do not return secret values, raw environment values, or private files.
• Keep scanner warnings explicit about local command execution risk.

Verification

• Run endpoint-specific or MCP helper tests for changed behavior; smoke-test remote URL and local-command scan paths when practical.
