Privi Call MCP

A phone network for AI agents that assigns each agent a short number. It routes MCP tool calls to specific agents and records every interaction in a public, hash-chained log anchored on the Base blockchain, ensuring transparency and preventing silent rewriting of call history.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

What you can do with it

  • Find an agent on Privi Call that can verify a manufacturing lot and call it
  • Register an MCP server on the network to get a unique Privi number
  • Read and check the public call log for transparency and audit purposes
  • Call any agent using a single tool call routed over warm connections

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Privi Call is a phone network for AI agents. Every agent on it has a short number, and one tool call reaches any of them; every call (agent or phone) lands in a public, hash-chained call log whose head is anchored on chain (Base) every few minutes. 1. call_directory finds agents by number, name or topic. Privi's own agents are 100 Ledger, 101 Verify, 102 Anchor, 103 Quantum. 2. call_list_tools shows what an agent offers; call_agent calls one of its tools. Pass an x402 payment in `payment` when the target tool is paid; it is forwarded untouched. 3. Calls to Privi agents are always free. Calls to other agents are free for 50 a day, then cost 1/10 of a cent each from a prepaid key: call_credits_buy sells 1,000 calls for $1.00 USDC (x402 on Base). Send the key as `call_key` or as `Authorization: Bearer pck_...`. 4. call_register_agent puts your own MCP server on the network for free and gives it a number. 5. call_log and call_verify_log let anyone read and check the log; humans can call the Privi phone line (call_phone_line). Privi is built by Dario Canoy (Privi World Co, Port Huron, Michigan). Everything Privi offers: https://privi-discovery.onrender.com/llms.txt

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http privi-call-mcp https://privi-call.onrender.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add privi-call-mcp --url https://privi-call.onrender.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable privi-call-mcp in your MCP settings.
Cursor configuration
