# go-ai MCP Tool Reference

**Module**: `forge.lthn.ai/core/go-ai`

This document is the authoritative reference for every MCP tool exposed by the go-ai hub. It is generated from the source definitions in `mcp/` and `mcp/ide/`.

---

## Overview

go-ai exposes **49 tools** across 13 functional groups via the [Model Context Protocol](https://modelcontextprotocol.io/). The server can be started in two modes:

- **Stdio** (default): `core mcp serve` — standard MCP transport for use with Claude, Cursor, and other MCP clients.
- **TCP**: `MCP_ADDR=:9000 core mcp serve` — listens on a TCP socket for programmatic access.

### Registration model

Tools are registered in two tiers:

1. **Built-in tools** (registered unconditionally in `mcp.New()`): file operations, directory operations, language detection, RAG, metrics, and webview tools. These are always present regardless of configuration.

2. **Subsystem tools** (registered via `WithSubsystem()`): ML, process management, WebSocket, and IDE tools. These require the corresponding backend service to be provided via an `Option` at construction time. Process and WebSocket tools are silently omitted if their respective services are not supplied. IDE tools are provided by the `ide.Subsystem` subsystem.

### Workspace sandboxing

All file and directory tools operate within a sandboxed filesystem medium. By default the sandbox root is the current working directory at the time `mcp.New()` is called. The root can be changed with `WithWorkspaceRoot(path)`. All paths supplied to file tools are validated to remain within this root — path traversal attempts are rejected.

### Audit logging

Every tool execution is logged. Tools that perform writes, process control, or browser automation are logged at `Security` level. Read-only tools are logged at `Info` level.

## File Operations

Six tools for reading, writing, editing, renaming, deleting, and checking files. All paths are resolved relative to the configured workspace root and must not escape it.

---

### `file_read`

Read the contents of a file.

**Parameters**

| Field | Type | JSON key | Required | Description |
|---|---|---|---|---|
| Path | `string` | `path` | Yes | Path to the file, relative to workspace root |

| Language | `string` | `language` | Detected language ID (see `lang_detect`) |
| Path | `string` | `path` | Echoed input path |

**Notes**

The language field is populated by extension-based detection and will be `"plaintext"` for unrecognised extensions. The call fails if the path does not exist or points outside the workspace root.

---

### `file_write`

Write content to a file, creating it and any intermediate directories if they do not exist.

**Parameters**

| Field | Type | JSON key | Required | Description |
|---|---|---|---|---|
| Path | `string` | `path` | Yes | Destination path, relative to workspace root |
| Content | `string` | `content` | Yes | Content to write |

**Response**

| Field | Type | JSON key | Description |
|---|---|---|---|
| Success | `bool` | `success` | Whether the write succeeded |
| Path | `string` | `path` | Echoed input path |

**Notes**

Overwrites any existing file at the given path without warning. Parent directories are created automatically. Logged at `Security` level.

---

### `file_edit`

Edit a file by replacing one occurrence (or all occurrences) of `old_string` with `new_string`. The file must already exist.

**Parameters**

| Field | Type | JSON key | Required | Description |
|---|---|---|---|---|
| Path | `string` | `path` | Yes | Path to the file |
| OldString | `string` | `old_string` | Yes | Exact string to find; must not be empty |

**Notes**

Returns an error if `old_string` is empty or is not found in the file. With `replace_all=false` (default) only the first occurrence is replaced and `replacements` will be `1`. With `replace_all=true` all occurrences are replaced and `replacements` reflects the total count.

---

### `file_delete`

Delete a file or empty directory.

**Parameters**

| Field | Type | JSON key | Required | Description |
|---|---|---|---|---|

|---|---|---|---|
| Exists | `bool` | `exists` | Whether the path exists |
| IsDir | `bool` | `isDir` | Whether the path is a directory |
| Path | `string` | `path` | Echoed input path |

**Notes**

Returns `exists=false` for paths that do not exist or are inaccessible. Does not distinguish between a missing path and a permission error.

---

## Directory Operations

Two tools for listing and creating directories within the workspace.

---

### `dir_list`

List the contents of a directory.

**Parameters**

| Field | Type | JSON key | Required | Description |

**Supported languages**

`typescript`, `javascript`, `go`, `python`, `rust`, `java`, `php`, `ruby`, `html`, `css`, `json`, `yaml`, `markdown`, `sql`, `shell`

The full detection set (including `c`, `cpp`, `csharp`, `scss`, `xml`, `swift`, `kotlin`, `dockerfile`) is available via `lang_detect` but is not enumerated by `lang_list`.

---

## RAG — Vector Search

Three tools for semantic document retrieval and ingestion. These tools require:

- **Qdrant** running at `localhost:6334` (default gRPC port)
- **Ollama** running at `localhost:11434` for embedding generation

The default collection name is `hostuk-docs`.

---

### `rag_query`

| Status | `string` | `status` | Qdrant collection status (only present when `show_stats=true`) |

**Notes**

Opens a short-lived Qdrant client connection per call. Stats are fetched per-collection and failures for individual collections are logged and skipped rather than aborting the entire response.

---

## ML — Inference & Scoring

Five tools for text generation, response scoring, capability probing, pipeline status, and backend enumeration. These tools are provided by the `MLSubsystem` and require a configured `go-ml` service instance (`ml.Service`).

The generation path is: `go-ai` → `go-ml.Service.Generate` → `InferenceAdapter` → `inference.TextModel` (from `go-inference`).

---

### `ml_generate`

| MaxTokens | `int` | `max_tokens` | No | Maximum tokens to generate |

**Response**

| Field | Type | JSON key | Description |
|---|---|---|---|
| Response | `string` | `response` | Generated text |
| Backend | `string` | `backend` | Backend used |
| Model | `string` | `model` | Model used (if applicable) |

**Notes**

Returns an error if `prompt` is empty. Backend selection falls through to the service default when `backend` is not specified. Available backends can be queried with `ml_backends`.

---

### `ml_score`

Score a prompt/response pair using one or more scoring suites.

**Parameters**

| Field | Type | JSON key | Required | Description |
|---|---|---|---|---|
| Prompt | `string` | `prompt` | Yes | The original prompt |
| Response | `string` | `response` | Yes | The model response to evaluate |

| Semantic | `*ml.SemanticScores` | `semantic` | LLM judge scores (present when requested) |
| Content | `*ml.ContentScores` | `content` | Content scores (not available via this tool; use `ml_probe`) |

**Notes**

`heuristic` scoring requires no backend. `semantic` scoring requires a judge backend to be configured in the ML service; the call returns an error if none is present. The `content` suite is not supported by this tool — use `ml_probe` instead. Both `prompt` and `response` must be non-empty.

---

### `ml_probe`

Run capability probes against an inference backend. Each probe sends a structured prompt to the backend and records the response.

**Parameters**

| Field | Type | JSON key | Required | Description |
|---|---|---|---|---|
| Backend | `string` | `backend` | No | Backend name; uses service default if omitted |
| Categories | `string` | `categories` | No | Comma-separated category names to filter probes; all categories run if omitted |

**Response**

| Field | Type | JSON key | Description |
|---|---|---|---|
| Total | `int` | `total` | Number of probes executed |

|---|---|---|---|
| ID | `string` | `id` | Probe identifier |
| Category | `string` | `category` | Probe category |
| Response | `string` | `response` | Backend response, or an error string prefixed with `"error: "` |

**Notes**

Probes are drawn from `ml.CapabilityProbes` defined in `go-ml`. Individual probe failures are captured as error strings in the response rather than aborting the entire run. Temperature is fixed at `0.7` and `MaxTokens` at `2048` for all probes.

---

### `ml_status`

**Prerequisite**: start Chrome with remote debugging enabled:

```
google-chrome --remote-debugging-port=9222
```

`webview_connect`, `webview_eval`, and `webview_navigate` are logged at `Security` level due to their capability to exfiltrate data or execute arbitrary code.

---
