Using io.github.samith14/mcp-cantina 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).

Install the mcpindex gate (one command)

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

Limits of this verdict

- 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

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.

Environment variables

MOSAISLEY_API

Base URL of the cantina REST API. Defaults to https://mosaisley.com. Override for local dev (e.g., http://localhost:8472).

MOSAISLEY_PATRON_ID

Stable patron identity (any string; an EVM address recommended). If unset, a fresh random ID is generated per process and reused for the session.

PAYMENT_SIGNATURE

x402 payment signature header sent on paid endpoints. Defaults to 'stub' (works against PAYMENT_MODE=stub cantinas). For live x402 the client should intercept 402 responses and sign — see https://github.com/samith14/mos-aisley-cantina/blob/main/server/examples/pay-as-an-agent.ts
