Endpoint Security57
Transport & Reachability100
Schema Quality & AI Usability67
  • AI-judged instruction clarity (good).Pass
  • Tool/resource definitions use about 581 tokens (~64/item across 9 items; 9 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
  • No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 0% of tool parameters carry a description.Fail
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the io.github.jdhart81/agent-erc8004-bridge MCP server?

io.github.jdhart81/agent-erc8004-bridge is a hosted endpoint at https://mcp.viridisconservation.com/erc8004/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.

    No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools · 9 exposed · ~521 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 →

Common questions

What is the io.github.jdhart81/agent-erc8004-bridge MCP server?

io.github.jdhart81/agent-erc8004-bridge is an MCP server listed in the public MCP registry as io.github.jdhart81/agent-erc8004-bridge. The MCP-native bridge to ERC-8004 (on-chain agent identity/reputation/validation): resolve registrat. This page covers its hosted endpoint (https://mcp.viridisconservation.com/erc8004/mcp).

Is the io.github.jdhart81/agent-erc8004-bridge MCP server safe to use?

io.github.jdhart81/agent-erc8004-bridge scores 75 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.jdhart81/agent-erc8004-bridge MCP server expose?

io.github.jdhart81/agent-erc8004-bridge exposes 9 tools: import_registration, resolve_agent, import_feedback, score_agent, bind_identity, and 4 more. Their descriptions and schemas cost roughly 521 tokens of context every time the server is loaded.

Does the io.github.jdhart81/agent-erc8004-bridge MCP server require authentication?

No. We connected to io.github.jdhart81/agent-erc8004-bridge without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the io.github.jdhart81/agent-erc8004-bridge MCP server still maintained?

io.github.jdhart81/agent-erc8004-bridge is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
