Hello MCP Server (celfons/mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
A stateless MCP server for Cloudflare Workers that uses createMcpHandler to expose a simple greeting tool, requiring no persistent state.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Tool 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
59/59 tools missing one or more hints — ping (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); facebook_list_pages (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); facebook_get_page (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +56 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.
Tool handlers catch errors
Only 0/1 tool handlers wrap calls in try/catch (0%)
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.
Domain consistency
npm scope @cloudflare doesn't match GitHub owner celfons
Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.
