[go165]

Summary

• Fixes mcp-server-fetch hard-codes use_readability=True which requires Node.js (undeclared); fails silently when Node is unavailable or misconfigured #4199
• Default the fetch server HTML simplifier to readabilipy's Python backend with use_readability=False
• Keep the existing error marker behavior when simplified content is blank
• Update the fetch README to state the default simplifier does not require Node.js

Verification

• /tmp/mcp-fetch-test-venv/bin/python -m pytest src/fetch/tests/test_server.py
• /tmp/mcp-fetch-test-venv/bin/python -m compileall -q src/fetch/src/mcp_server_fetch src/fetch/tests
• /tmp/mcp-fetch-test-venv/bin/python -m ruff check src/fetch/src/mcp_server_fetch/server.py src/fetch/tests/test_server.py
• git diff --check

Thank you for this pull request, and apologies for the long wait for a response.

Since it was opened, the reference servers have been rebuilt for the 2026-07-28 MCP specification (#4857) and released as v2, so this diff no longer applies to the code as it stands. This repository also now accepts issues, not pull requests, from anyone but its maintainers: design and implementation are done by the maintainers through a prompt-driven workflow, so outside PRs are closed rather than reviewed. The policy is in CONTRIBUTING.md.

This is not a judgment on the change or on you. The problem it addresses still applies to v2 and is tracked in #4199, which links back to this PR as a prototype and credits you. Please add anything further there.

This is part of the backlog triage in #4875.
