How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →

Endpoint Security89
Transport & Reachability100
Schema Quality & AI Usability74
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 3381 tokens (~147/item across 23 items; 23 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management10
  • Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 23 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass

Install

How do I install the io.usefulapi/momence MCP server?

io.usefulapi/momence is a hosted endpoint at https://momence.usefulapi.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Common questions

What is the io.usefulapi/momence MCP server?

io.usefulapi/momence is an MCP server listed in the public MCP registry as io.usefulapi/momence. Look up Momence members, class schedules, bookings and memberships, and handle front-desk actions. This page covers its hosted endpoint (https://momence.usefulapi.io/mcp).

Is the io.usefulapi/momence MCP server safe to use?

io.usefulapi/momence scores 77 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.usefulapi/momence MCP server expose?

io.usefulapi/momence exposes 23 tools: momence_get_current_user, momence_list_members, momence_get_member, momence_list_member_session_bookings, momence_list_member_appointments, and 18 more. Their descriptions and schemas cost roughly 3,381 tokens of context every time the server is loaded.

Does the io.usefulapi/momence MCP server require authentication?

Yes. io.usefulapi/momence asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

Is the io.usefulapi/momence MCP server still maintained?

io.usefulapi/momence is still listed as active in the MCP registry. We last reached this channel on 3 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
