render_mcp
A guide to deploy a remote MCP server on Render.com and connect it to Anthropic and OpenAI agents, enabling cloud-hosted tool access for AI models.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
search_papersEnhanced search for papers on arXiv with advanced filtering options.
search_by_authorSimplified tool specifically for author searches. Args: author_name: Full name of the author to search for max_results: Maximum number of results (default: 10) sort_by: Sort criterion (default: submittedDate) Returns: Dict with search results
search_recent_papersSearch for recent papers on a topic within the last N days. Args: topic: The research topic to search for days_back: Number of days to look back (default: 7) max_results: Maximum number of results (default: 10) Returns: Dict with recent papers
extract_infoSearch for information about a specific paper across all topic directories.
get_current_weatherGet current weather information for a specific location.
get_weather_forecastGet weather forecast for a specific location.
get_weather_historyGet previously saved weather data for a location.
PORTTool 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
7/7 tools missing one or more hints — search_papers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_by_author (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_recent_papers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 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.
Descriptions match behaviour
1 tool describes read intent but its handler mutates — search_papers (line 188: with open(file_path, "w", encoding='utf-8') as json_file:)
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool handlers catch errors
5/7 tool handlers wrap calls in try/catch (71%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Tool description accuracy
search_papers: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
