The current version, v0.0.3, was published to the official MCP registry on 2026-08-09. It is distributed as @mosaisley/mcp-cantina on npm, filed under Other by this index, and declares 6 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.

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

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 2026-08-27).
Contracts can change after screening, with no version bump. The gate pins io.github.samith14/mcp-cantina’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.

Defaults to https://mosaisley.com. Override for local dev (e.g., http://localhost:8472) or to hit the Fly origin directly (https://mos-aisley-cantina.fly.dev).
MOSAISLEY_PATRON_IDStable patron identity (any string; an EVM address recommended). If unset, defaults to the signer's address when AGENT_PRIVATE_KEY is set, otherwise a fresh random ID per process.
AGENT_PRIVATE_KEYOptional 0x-prefixed EVM private key. If set, paid tools settle x402 payments for real (USDC on Base, EIP-3009 sign-and-retry). HOT WALLET — fund with pocket change only; the key never leaves the process and is never logged.
MAX_SPEND_CENTSPer-payment spend cap in cents when AGENT_PRIVATE_KEY is set. Default 100 ($1.00). Payments above the cap are refused, never signed.
MAX_SESSION_SPEND_CENTSCumulative spend cap in cents for the life of this MCP process. Default 500 ($5.00). Bounds total drain across many under-cap payments; restart to reset.
PAYMENT_SIGNATUREHeader value sent on the automatic retry against a cantina in PAYMENT_MODE=stub (local dev only; the stub accepts any value). Defaults to 'stub'. Irrelevant in live mode — use AGENT_PRIVATE_KEY there.
