# Experimental MCP

> The extension boundary in Fella's lean personal release.

# The extension door is closed for this release

Fella's personal release is intentionally small. It mounts a folder, uses a
fixed set of read-only tools, and returns answers with evidence and
verification. There is no pack manager, plugin runtime, or official connector
system in the shipped application.

## MCP is experimental and inert

The `/mcp` command is a signpost for future work. Its only supported response
is:

```text theme={null}
MCP is experimental and closed in this release.
No official connectors are enabled.
Custom implementations require a fork or experimental build.
```

The default build does not include an MCP client, connector authentication,
dynamic tool discovery, outbound connector connections, or an MCP marketplace.
The built-in agent registry contains only Fella's fixed local tools.

## What remains extensible

The product boundary is documented so a future implementation has a clear seam:

* `fella.md` is a user-authored context file in the mounted folder.
* The agent remains read-only and cannot create workspace files.
* A fork or experimental build may add a reviewed connector implementation.
* Any future connector must declare its data access, network destinations,
  write behavior, limits, enablement flow, and evidence behavior.

Custom builds are the user's responsibility. A connector should not become an
official Fella feature merely because it speaks the MCP protocol; it must also
fit the local-first, bounded, auditable request path.

## Removed from the personal release

The following surfaces are intentionally absent from the default build:

* Packs and the `fella-extensions` marketplace relationship.
* `/packs` and `/connect`.
* Augment tabs, `/note`, and `/table`.
* Dynamic tools supplied by a user-installed extension.
