[ Agents ]

Quick MCP

Connect an agent to the layer in one line. The MCP server answers without a key; its taifoon_register tool issues one.

claude mcp add --transport http taifoon https://coord.taifoon.dev/mcp

First call from any MCP client: tools/list, then taifoon_proof_tx with a chain and a transaction hash.

Free to start, metered after

unit	free a day (key / visitor)	USDC per 1M	GRID per 1M
one JSON-RPC request (a batch of up to 20 calls is one request)	1000 / 100	0.500000	25
one request that returns a block proof (taifoon_getProof, or any request sent with x-taifoon-proof: 1)	0 / 0	5.000000	250

[ Partnership ]

Run Celo with Taifoon

A chain or protocol team can claim the owner seat of its record: it then maintains its lanes and stage table, sets its pricing share, and the Conclave records the ownership and the share. Endpoint operators can add capacity to the rotation and earn per call.

curl -s https://coord.taifoon.dev/v1/owners/chain:42220

Claim: POST https://coord.taifoon.dev/v1/owners/chain:42220/claim with your key and a signature from an address your contracts name. Partner cards · add capacity.
