The file protocol for AI agent context. Encrypted, signed, peer-to-peer.
Openfused MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. The file protocol for AI agent context. Encrypted, signed, peer-to-peer.
AI agents lose their memory when conversations end. Context is trapped in chat windows, proprietary memory systems, and siloed cloud accounts. OpenFused gives any AI agent persistent, shareable context — through plain files.
Once Openfused is connected, these are the calls the assistant has available:
Hardening — The Hardening tool exposed by this serverBeing a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need 2 environment variables: OPENFUSE_TOKEN, TUNNEL_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Openfused's toolset — Hardening — is a fair guide to whether it matches your workflow. It is maintained by wearethecompute; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
