## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## MCP tools (4)

### `fuuga_delegate` (~121 tokens)

Delegate a small, well-scoped errand to the local Fuuga minion. Returns structured JSON {status, output, files_changed, escalate, reason, confidence, verification}. If the minion is unsure, or the configured verify command (build/tests) still fails on its changes, it sets escalate=true so the master should take over.

Input parameters:

- `files` (array): Optional workspace files to load as context
- `max_steps` (integer): Max tool-call rounds (default 8)
- `task` (string, required): The errand to carry out

### `read_file` (~38 tokens)

Read a UTF-8 text file from the workspace and return its contents.

Input parameters:

- `path` (string, required): Workspace-relative or absolute path to the file

### `list_dir` (~40 tokens)

List the files and subdirectories of a directory in the workspace.

Input parameters:

- `path` (string): Workspace-relative or absolute directory path. Defaults to the workspace root.

### `grep` (~72 tokens)

Search workspace files for lines matching a regular expression. Returns path:line:text matches.

Input parameters:

- `glob` (string): Optional filename glob filter, e.g. *.fs
- `path` (string): Directory or file to search under. Defaults to the workspace root.
- `pattern` (string, required): Regular expression to search for

## Common questions

### What is the Fuuga minion MCP server?

Fuuga minion is an MCP server listed in the public MCP registry as io.github.Thorium/fuuga. Offline local-LLM helper: delegate simple errands to a local model, with sandboxed file tools. This page covers its NuGet package (Fuuga.Server.cpu).

### Is the Fuuga minion MCP server safe to use?

Fuuga minion scores 75 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Fuuga minion MCP server expose?

Fuuga minion exposes 4 tools: fuuga_delegate, read_file, list_dir, grep. Their descriptions and schemas cost roughly 271 tokens of context every time the server is loaded.

### Is the Fuuga minion MCP server still maintained?

Fuuga minion is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Fuuga minion MCP server under?

Fuuga minion declares the Unlicense licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
