# KMP

Local-first agent memory that preserves what happened, when and why

The current version, v0.5.1, was published to the official MCP registry on 2026-08-29. It is distributed through a declared package, filed under Memory & RAG by this index, and declares 3 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](/stats) put this record in context.

## Using KMP 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).

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
```

[method](/methodology)

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](/methodology).

## That verdict was true at screening time (snapshot 2026-08-29).

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