HSM-backed vault secrets for AI agents (JIT fetch) plus prompt-injection and threat scanning.
The current version, v0.52.0, was published to the official MCP registry on 2026-08-18. It is distributed as @1claw/mcp on npm, filed under Security by this index, and declares 5 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
uv tool install mcpindex-gate && mcpindex-config-wire
Semantic screen flagged a possible manipulation pattern in the description; review before your agent calls this tool.

- The registry listing (version, packages, links) changed after this screen ran - the description we assessed did not
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 2026-08-18). #
Contracts can change after screening, with no version bump. The gate pins 1Claw Vault’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.

ONECLAW_AGENT_API_KEY
Agent API key (ocv_...). Exchanged for a short-lived JWT; auto-discovers agent ID and vault. Recommended for stdio.
ONECLAW_AGENT_ID
Optional agent UUID when pinning identity (usually auto-discovered from the API key).
ONECLAW_VAULT_ID
Optional vault UUID when the agent can access multiple vaults.
ONECLAW_BASE_URL
Vault API base URL (default https://api.1claw.xyz).
ONECLAW_LOCAL_ONLY
Set to true for security-only mode (inspect_content only; no vault credentials).
