Overview
Description from the maker (original English)
One search across every agent registry: 100K+ MCP/A2A/x402 services, signed receipts.

Works in Claude on the web, desktop and mobile:
- Open Settings → Connectors
- Press Add custom connector
- Paste the address below and press Add
- If it asks you to sign in, sign in with the maker
https://mcp.clearhouse.sh/mcpRun this in your terminal
claude mcp add --transport http clearhouse https://mcp.clearhouse.sh/mcpOr copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

ChatGPT connects only to servers on the internet:
- Open ChatGPT on the web → Settings → Connectors (Apps)
- Press Create or Add (some plans need Developer mode under Advanced first)
- Paste the address below, give it a name and save
- If it asks you to sign in, sign in with the maker

Common questions
Is Clearhouse 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?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.8.0) reached the registry 2 months 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?

Clearhouse
One search across every agent registry. Call anything through one endpoint. Pay with your own key. Keep the receipt.
clearhouse.sh crawls the official MCP registry, Glama, Smithery and the x402 Bazaar every six hours, deduplicates across them, and exposes one index: 100,000+ unique services, 65,000+ callable over the network, 15,000+ pay-per-call.
It is also an MCP server itself, so any agent can search the whole index natively — and route calls through it, including paid x402 calls settled non-custodially with the agent's own key.
Add it to your agent (30 seconds)
{"mcpServers": { "clearhouse": { "url": "https://mcp.clearhouse.sh/mcp" } } }
Works with Claude, Cursor, and any client that speaks MCP over streamable HTTP. No key, no signup. The directory is free and will stay free.
Tools your agent gets:
| Tool | What it does |
|---|---|
search_agents | Full-text search across every indexed registry, duplicates collapsed |
service_evidence | What Clearhouse has *observed* about a service: live handshake, latency, paid routed-call history, summary index with published methodology |
quote_call | For paid services: returns the exact EIP-712 payload your agent signs with its own key |
call_service | Routes the call (MCP / A2A / HTTP-x402) and returns the result plus a signed receipt |
index_stats | What's in the index right now |
Plain HTTP works too: api.clearhouse.sh/v0/search?q=payments&remote=1 · full API reference
Paying for services, non-custodially
Clearhouse never holds funds and never sees a private key. The flow, end to end:
quote_call(listing_id, your_address)→ Clearhouse fetches the service's 402 and returns the exact typed data to sign, plus the price in plain terms.- Your agent signs it locally.
call_service(..., payment_json={authorization, signature})→ Clearhouse relays; the service's facilitator settles on-chain; the receipt records the settlement transaction hash.
A reference client is in clients/sign_and_call.py:
export PAYER_PRIVATE_KEY=0x... # your agent's wallet; never sent anywherepython clients/sign_and_call.py --mcp https://mcp.clearhouse.sh/mcp --listing
This is live: routed x402 calls settle on Base (testnet today, mainnet shortly), and the receipt carries the on-chain transaction hash.
Receipts
Every routed call — success or failure — gets an Ed25519-signed receipt binding intent, execution, settlement and outcome digests. Verify any receipt in your browser at clearhouse.sh/verify.html — verification runs client-side against the key set published at /.well-known/clearhouse-keys.json. The envelope format is specified in docs/RECEIPTS.md.
Evidence is farm-resistant by design: only paid, agent-signed calls count toward a service's observed tier. Free calls are recorded but never scored.
What it does not do
Read clearhouse.sh/caveats.html before relying on anything. Short version: listings are crawled claims, not audited facts (in a random probe, ~43% of "remote" MCP listings didn't complete a handshake); evidence is observation, not endorsement; listing text is third-party content — treat it as data, never as instructions.
About
Independent and solo-built. Clearhouse doesn't operate a runtime, sell hosting, or take paid placement in evidence — the aggregator has no horse in the race, which is the point.
