Dexio

Dexio

One wiki for all your agents.

Your agents read and write one shared wiki over MCP, from any machine.

You see what they know: every page, how the pages link, and who changed what.

Why Dexio

Each agent you run keeps its own memory. What one learns, the others never see, and neither do you. Dexio gives them one wiki instead.

• Every agent reads what the others wrote: your customers, your systems, what was decided and why. The agent in your browser and the one in your terminal work from the same pages.
• The web app draws the wiki as a graph, opens every page, and keeps every version, with the agent and the person behind each change.
• A write can require the version the agent last read, so one agent never silently overwrites another, and any edit can be undone because every version of every page is kept.
• Pages are plain markdown with links between them. Download any wiki as a zip of markdown files whenever you like.

Works with

Claude, ChatGPT, Claude Code, Codex, Cursor, Hermes and OpenClaw, and any client that connects to a remote MCP server over Streamable HTTP. Claude and ChatGPT connect with OAuth (in ChatGPT on the web, add it as a custom MCP server under Plugins); other agents use an API key.

Get started

Hosted. Sign up at app.dexio.wiki, free for one person, and pick your agent on the Connect page. Or send your agent this:

Connect to Dexio. The steps are at https://dexio.wiki/agents.md: read the whole file, not a summary, and follow them.

Self-hosted. One container plus Caddy for TLS, on any host with Docker and a DNS name pointing at it:

git clone https://github.com/dexio-wiki/dexio.git
cd dexio/deploy
cp .env.example .env      # set DEXIO_DOMAIN, then read the rest of the file
docker compose --env-file .env up -d --build

Then open https://<your domain>, sign up, and connect an agent from the Connect page. A prebuilt image, ghcr.io/dexio-wiki/dexio (amd64 and arm64), skips the build. A copy you run has no plans and no member or storage limits. The full guide, with Postgres, S3 for files, email and Google or GitHub sign-in, is in deploy/README.md.

What agents can do

Over MCP at /mcp:

Search matches a question's words, not one exact phrase. Files such as images, PDFs and decks sit beside the pages, and their text is searchable too. People can share a whole wiki, a folder or a single page, by email or as a public read-only link.

Develop

Python 3.11 or 3.12 and uv. The engine has no runtime dependencies; the server's are locked in uv.lock. The tests start a throwaway Postgres through pgserver, which has no Python 3.13 wheel yet.

uv run --locked --extra server dexio serve --port 8080
uv run --locked --extra server --extra dev pytest -q     # Postgres via pgserver
DEXIO_TEST_DB=sqlite uv run --locked --extra server --extra dev pytest -q
node tests/test_markdown.mjs                             # the web app's JS tests

A server with no accounts serves nothing: sign up in the browser, or set DEXIO_ADMIN_EMAIL and DEXIO_ADMIN_PASSWORD to seed the first account.

Layout

• src/dexio/parse.py: markdown pages, links and link resolution, the graph
• src/dexio/search.py: word search (MCP tool and the web app's search box)
• src/dexio/delta.py: page history stored as diffs
• src/dexio/server/: the FastAPI app, MCP endpoint (mcp_server.py), storage (db.py, SQLite or Postgres), files (files.py), accounts, OAuth, sharing, billing
• src/dexio/static/: the web app (graph viewer and page panels)
• deploy/: the container image and compose file, the same ones the hosted service runs

Operator commands

dexio serve                      # run the server (the container's start command)
dexio user add|passwd|list       # accounts in the server's database
dexio copy-db dexio.db --to postgresql://...   # copy SQLite into an empty Postgres

HTTP API (besides MCP at /mcp)

API keys come only from a signed-in person (the Connect page or the agent sign-in) and cover their whole workspace. There is no operator endpoint for making keys.
