CurveCall MCP

CurveCall provides market math and token intelligence for AI agents via pay-per-call endpoints. It offers bonding-curve quotes, rug-risk screening, contract checks, and deployer history analysis. The MCP server allows agents to execute these checks using USDC on Base for settlement, requiring no API keys or accounts.

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 its tools do

11 tools, grouped by the hints the server advertises. Hints are self-declared, not verified behavior.

11 of 11 have a description · 0 of 11 declare behavior hints · 0 of 11 with parameters document them all

Checks and signals

Each line is separate evidence, not a trust score.

Server-provided instructions

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

Pay-per-call market math and token intel, paid in USDC via x402 on Base. Every tool requires an x402 payment: call without `payment` to get the PaymentRequired JSON, pay it, then retry passing the payment payload (base64) in `payment`. START HERE: the verdict tool (buy/watch/avoid in one call - bundles risk + deployer + holders + trade simulation, with reasons and sizing); precheck returns the full raw bundle: snapshot + risk screen + trade simulation in one call - what your buy will DO, not just the price. Plus on-chain contract checks (ownership renounced, LP burn), wallet snapshots and token search.
