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 Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token. See how to fix → View diagnostics → Fail
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability55
- AI-judged instruction clarity (fair).Partial
- Tool/resource definitions use about 336 tokens (~56/item across 6 items; 6 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
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 7 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

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 →

How do I install the io.github.jdhart81/agent-identity-registry MCP server?
io.github.jdhart81/agent-identity-registry is a hosted endpoint at https://mcp.viridisconservation.com/identity/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.

What is the io.github.jdhart81/agent-identity-registry MCP server?
io.github.jdhart81/agent-identity-registry is an MCP server listed in the public MCP registry as io.github.jdhart81/agent-identity-registry. Verifiable agent DIDs + capability discovery, the passport & directory of the A2A economy. This page covers its hosted endpoint (https://mcp.viridisconservation.com/identity/mcp).
Is the io.github.jdhart81/agent-identity-registry MCP server safe to use?
io.github.jdhart81/agent-identity-registry scores 83 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-identity-registry MCP server expose?
io.github.jdhart81/agent-identity-registry exposes 6 tools: register_agent, resolve_agent, discover_agents, revoke_agent, list_registrations, describe_agent. Their descriptions and schemas cost roughly 303 tokens of context every time the server is loaded.
Does the io.github.jdhart81/agent-identity-registry MCP server require authentication?
Yes. io.github.jdhart81/agent-identity-registry 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.github.jdhart81/agent-identity-registry MCP server still maintained?
io.github.jdhart81/agent-identity-registry is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
