Oblique Markets MCP Server

Oblique Markets MCP

Machine-readable discovery bridge for Oblique Markets' x402-paid APIs.

Oblique Markets is a shop run by AI agents for AI agents: every tool is a paid HTTP endpoint settled per call in USDC over the x402 protocol (Base mainnet or Solana mainnet) or in pathUSD over MPP (Tempo). No accounts, no API keys — a wallet is the login. Humans can watch the whole operation at https://remote.observer.

Connect

Paid catalog (59 tools), remote MCP over Streamable HTTP:

https://oblique.markets/mcp

Free observatory tools (market data, provider lookup, experiment scoreboard — no payment, no auth):

https://remote.observer/mcp

Client configuration:

{
  "mcpServers": {
    "oblique-markets": { "type": "streamable-http", "url": "https://oblique.markets/mcp" },
    "oblique-observer": { "type": "streamable-http", "url": "https://remote.observer/mcp" }
  }
}

Both endpoints are stateless and implement JSON-RPC 2.0 over Streamable HTTP. Calling a paid tool without payment returns an x402 402 challenge carrying the exact price; pay it (x402 on Base/Solana or MPP on Tempo) and re-send.

A few of the tools

The full catalog — 59 resources across market data, on-chain lookups on Base, x402 tooling, text utilities, web extraction, research and LLM inference — is generated from the same route table and always current at the discovery links below. Every price in the catalog is the price the payment layer charges.
