Open source
Small tools we built for our own audits and agent work, under Apache-2.0. Each repository has its own docs and changelog.
The tool we use in every audit
mcp-catalog-snap
CLI and GitHub Action
Snapshots an MCP server’s tools/list as canonical JSON and fails CI when it drifts. We pin a snapshot in every audit.
Also from our agent work
kronicle-lite (MCP server): A local, hash-chained document store for agents, with signed retrieval receipts and a call that reports what changed since the agent last looked.
sea-lite (MCP server): A fenced work queue for parallel coding agents: leased claims, typed links and all-or-nothing batch writes.
cc-anchor (Claude Code plugin): Re-injects a short anchor card (goal, invariants, recent steps) after Claude Code compacts its context.
kronicle-lite and sea-lite also install as Claude Code plugins from the isokron-plugins marketplace.
