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 Security57
Transport & Reachability100
Schema Quality & AI Usability72
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 223 tokens (~55/item across 4 items; 4 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management13
  • Stability observed for 4 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 Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "defigent_inbox_send" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
  • An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a current MCP spec version (2026-07-28).Pass
Changelog

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

  • 16 Oct 26 +1

    No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools · 4 exposed · ~223 tokens

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 →

Install

How do I install the io.github.Firrton/defigent MCP server?

io.github.Firrton/defigent is a hosted endpoint at https://opacus-liana-lanceted.ngrok-free.dev/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.

Common questions

What is the io.github.Firrton/defigent MCP server?

io.github.Firrton/defigent is an MCP server listed in the public MCP registry as io.github.Firrton/defigent. Agent messaging inbox (A2A, EIP-712 signed), ERC-8004 directory, status and text hashing for Monad. This page covers its hosted endpoint (https://opacus-liana-lanceted.ngrok-free.dev/mcp).

Is the io.github.Firrton/defigent MCP server safe to use?

io.github.Firrton/defigent scores 64 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.github.Firrton/defigent MCP server expose?

io.github.Firrton/defigent exposes 4 tools: defigent_hash, defigent_inbox_send, defigent_network_list, defigent_status. Their descriptions and schemas cost roughly 223 tokens of context every time the server is loaded.

Does the io.github.Firrton/defigent MCP server require authentication?

No. We connected to io.github.Firrton/defigent without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the io.github.Firrton/defigent MCP server still maintained?

io.github.Firrton/defigent is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
