# kcp-agent — KCP navigation planner MCP Server Deterministic, fail-closed planner for KCP knowledge manifests: kcp_plan, kcp_load, kcp_validate. **Publisher claimed.** No tool list reported, and Pod has not connected to this server. ## Status Pod has not dialled kcp-agent — KCP navigation planner yet, so everything on this page is what its publisher reported rather than what we observed. Registries describe servers; they do not connect to them. Until a check runs, treat the tool list below as a claim. ## Connect Published as `kcp-agent` on npm. Runs locally. ## Known issues **25 problems reported by people outside the maintainer team.** Issues filed by the project's own owners, members and collaborators are excluded — those are release checklists and internal refactors, not things that will go wrong for you. Showing 12. ### Most discussed ### Post-synthesis confidence gate — gate agent conclusions, not just knowledge access ## Problem We're piloting kcp-agent as the enforcement layer under an internal governance model for a small SaaS org ("Tillitsbro" below — anonymized) that lets human staff and AI agents jointly run customer-facing workflows. The model requires: *"critical tasks must halt if the agent's own confidence in its conclusion falls below a calibrated threshold — before the conclusion is acted on."* Concretely: an agent drafts a customer-facing risk assessment.

Meanwhile the world adopted **llms.txt** — a radically weaker cousin (a flat link list: no audiences, no temporal validity, no signatures, no payment, no federation) — at meaningful scale. That proves the publisher appetite exists; it just landed on the weakest possible format.

An empty result here is a gap in the corpus, not a verdict on the server.
