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

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.

That verdict was true at screening time (snapshot 2026-08-12).

Contracts can change after screening, with no version bump. The gate pins io.github.cyanheads/toolkit-mcp-server’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Environment variables

MCP_LOG_LEVEL

Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').

TOOLKIT_ENABLE_NET_DIAGNOSTICS

TOOLKIT_ENABLE_SYSTEM_INFO

TOOLKIT_ALLOW_PRIVATE_NETWORK

With network diagnostics enabled, permit private/reserved/loopback targets. The second explicit gate; off by default.

TOOLKIT_GEO_PROVIDER

IP-geolocation provider id. Default 'ip-api' is the keyless free tier.

TOOLKIT_GEO_API_KEY

secret

API key for the geolocation provider, if it requires one. The default ip-api tier is keyless.

TOOLKIT_GEO_BASE_URL

Base URL for the geolocation provider. Default is the keyless ip-api endpoint.

TOOLKIT_GEO_CACHE_TTL_SECONDS

Geolocation cache TTL in seconds. Geolocation is stable, so repeats are cached.

TOOLKIT_GEO_RATE_LIMIT_PER_MIN

Max geolocation requests per minute; excess requests are rejected with a retryable rate-limit error. Default 45 matches the ip-api free tier.

MCP_HTTP_HOST

The hostname for the HTTP server.

MCP_HTTP_PORT

The port to run the HTTP server on.

MCP_HTTP_ENDPOINT_PATH

The endpoint path for the MCP server.

MCP_AUTH_MODE

Authentication mode to use: 'none', 'jwt', or 'oauth'.

MCP_LOG_LEVEL

Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 962,093). Verify it yourself.
