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
curl -fsSL https://mcpindex.ai/install.sh | shSemantic 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

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.

LLM_API_BASEBase URL of an OpenAI-compatible /chat/completions endpoint; enables search(understand=true) and search(multi_query=true).
LLM_API_KEYBearer token for the LLM endpoint (LLM_API_BASE); omit for keyless local servers.
LLM_MODELModel name passed to the LLM endpoint (default: gpt-4o-mini); set to whatever your endpoint serves.
EMBEDDING_API_BASEBase URL of an OpenAI-compatible /embeddings endpoint; enables search(rank=semantic) re-ranking.
EMBEDDING_API_KEYBearer token for the embeddings endpoint (EMBEDDING_API_BASE); omit for keyless local servers.
EMBEDDING_MODELModel name passed to the embeddings endpoint (default: text-embedding-3-small).
UNPAYWALL_EMAILEmail address sent to the Unpaywall API; required to enable the Unpaywall PDF fallback leg of literature full-text retrieval.
