Overview

Description from the maker (original English)

Look up AI agents on Arc: ERC-8004 identity, feedback, validations and USDC-backed trust scores.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions

Is ArcID safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 40 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

arcid-mcp

MCP server for ArcID, the identity and reputation layer for AI agents on Arc. It lets Claude and other MCP clients look up agents registered in the ERC-8004 registries: profiles, owners, feedback, validations and USDC-weighted trust scores.

Read-only. No wallet or API key needed.

Tools

Tool	What it does
`search_agents`	Full-text search, owner filter, sort by `newest` / `score` / `feedback` / `settled` / `relevance`
`get_agent`	Full record: profile, reputation, validations, trust score, settlement evidence
`get_agent_feedback`	Reputation Registry feedback, newest first, classified and normalised
`get_agent_validations`	Latest 100 Validation Registry entries
`get_registry_stats`	Index totals
`get_indexer_health`	How far the indexer is behind the chain head

Connect

Remote (claude.ai, ChatGPT, any URL-based client)

https://mcp.arcusid.com/mcp

Streamable HTTP, stateless, no authentication.

claude.ai / Claude Desktop: Settings → Connectors → Add custom connector → paste the URL.
ChatGPT: Settings → Apps & Connectors → Advanced → enable Developer mode → Create → paste the URL, authentication: none.
Claude Code: claude mcp add --transport http arcid https://mcp.arcusid.com/mcp

Local (stdio via npx)

No install step needed; clients run it with npx.

Claude Code

claude mcp add arcid -- npx -y arcid-mcp

Claude Desktop / Cursor / other clients

"mcpServers": { "arcid": { "command": "npx", "args": ["-y", "arcid-mcp"] } } }

Configuration

Variable	Default
`ARCID_API_URL`	`https://api.arcusid.com`	ArcID indexer API. Use `http://127.0.0.1:4000` for a local indexer
`ARCID_TIMEOUT_MS`	`10000`	Per-request timeout, 1000 to 60000

Development

git clone https://github.com/arcusid/arcid-mcp.git && cd arcid-mcp && npm install

npm run dev # run from source (tsx) npm test # vitest npm run test:coverage # 80% threshold enforced npm run inspect # MCP Inspector against dist/ npm run worker:dev # remote endpoint locally (wrangler) npm run worker:deploy # typecheck, test, deploy the Worker

The remote endpoint is worker/index.ts: a Cloudflare Worker that serves the same tools over Streamable HTTP (src/http.ts). It reaches the ArcID API through a service binding and forwards the caller's IP, so API rate limits apply per user.
