In-path gate · all MCP tools

Using io.github.smeet666/mcp-books 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

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

Trust verdict · v1 advisory · method
NOT YET SCREENEDno verdict on file

Verdict not yet evaluated for this tool. The semantic screen takes adversarial cases first; coverage rolls out as the corpus expands (15/150 labels to graduation). The deterministic conformance probe is built but has not yet run on the public corpus, so a recorded verdict here is REVIEW or UNVERIFIED, never a clearing ALLOW. Until a verdict is recorded, an agent should treat this tool as not-yet-cleared and fall back to its own checks. Method: the eval, four-state verdict, honest limits.

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

Contracts can change after screening, with no version bump. The gate pins io.github.smeet666/mcp-books’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
BOOKS_USER_AGENT

Identify your own client. The project's own identifier is appended, so an archive can always reach a human.

BOOKS_MIN_INTERVAL_MS

Widen the gap between two requests to one archive. Each archive keeps its own spacing when this is unset, and this can only make it wider.

BOOKS_TIMEOUT_MS

Deadline for one request to an archive, in milliseconds. Default 45000.

BOOKS_MAX_RETRIES

Retries on rate limiting and transient failures. Default 3.

BOOKS_CACHE_TTL_MS

In-memory cache lifetime, in milliseconds. Default 900000. Set 0 to turn it off.

BOOKS_CACHE_MAX_ENTRIES

In-memory cache size. Default 200.

BOOKS_LOG_LEVEL

silent, error, info or debug. Default error. Logs go to stderr.
