Agentic Finance (AIFI): 500+ pay-per-call tools for AI agents over x402 + MPP, or free via PoW.

The current version, v0.12.7, was published to the official MCP registry on 2026-08-18. It is distributed as agent402-mcp on npm and as a hosted remote over streamable-http, filed under Finance & Payments by this index, and declares 3 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

Using Agent402.Tools — pay-per-call web tools in Claude, Cursor, Gemini CLI, Cline, or Zed? #

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

uv tool install mcpindex-gate && mcpindex-config-wire

Semantic screen found no manipulation pattern in the description. Conformance probe not yet run.

    • Semantic screen only - the deterministic conformance probe has not run on this server
    • Confidence is reported but not yet calibrated (v1)
    • Screen reads the tool description, not the live behavior
    • advisory
    • registry description only no input schema
    • screen model 8b
    • The description this screen assessed is no longer the one published
    • The registry listing (version, packages, links) changed after this screen ran - the description we assessed did not

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-08-18). #

Contracts can change after screening, with no version bump. The gate pins Agent402.Tools — pay-per-call web tools’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

People vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.
