Kindex MCP server

Kindex

Every agent is smart inside its own silo. Kindex lets them work together.

Kindex does one thing. It knows what you know.

Claude Code, Codex, Gemini CLI, Google Antigravity, OpenCode, Cursor, and other MCP-capable agents each remember for themselves, and none of them can read the others. Kindex is the local knowledge graph they all read and write: continuity across sessions and restarts, handoffs between vendors, shared decisions and constraints, and live coordination while several of them work at once. Available as a free MCP plugin or standalone CLI.

Memory plugins capture what happened. Kindex captures what it means and how it connects. Most memory tools are session archives with search. Kindex is a weighted knowledge graph with typed nodes, provenance, and decay, that surfaces constraints and decisions and manages exactly how much context to inject based on your available token budget.

Kindex is the index for an individual and a codebase: your own graph, and the repository's git-tracked .kin/. Kinbase is the company product above it, in development: engineering direction, architecture, standards, ownership, and history, held by named authorities and composed into every coding session. Same engine, same protocol, physically separate stores.

Docs: kindex.tools is the canonical public site, served by the companion Fly static app. This repo also publishes its docs/ directory at wandercom.github.io/kindex. Human setup lives in docs/human-guide.md; agent operating rules live in docs/mcp-agent-guide.md.

Install

Development preview: Claude function hooks and signet-eval coexistence adds repo-local durable tasks, secret minimization at Kindex-owned boundaries, and separately selectable modern/legacy adapters. The default remains compatible legacy hooks. Function hooks are qualified on Claude Code 2.1.274; this is not a promise that all Claude logs can be redacted or a published 1.0 release.

Pick whichever installer you already use. They all install the same kin and kin-mcp binaries.

# pip
pip install 'kindex[mcp]'

# uv (single binary, no virtualenv)
uv tool install 'kindex[mcp]'

# uvx (no install — runs from cache, useful for one-off MCP invocation)
uvx --from 'kindex[mcp]' kin-mcp --help

# from source
git clone https://github.com/wandercom/kindex && cd kindex && make install

Upgrading to v0.36.0

[!WARNING]

Before upgrading, stop every Kindex daemon, MCP server, and older CLI

process. A v0.35.x process does not reject schema v12 and can write

non-canonical session paths after migration.

Shortened. The full README is on GitHub.
