# get_file_claims

[SUPPORT] Read-only: show active claims on a file — the whole-file lock (with the holder's session name, if any) plus any symbol-level claims. Use to check who owns a file before editing it. Pass project_id (and optional symbol) to also get a code_notes list of code-anchored notes (kind='code') for that path.

- Homepage: https://github.com/meridianmcp/Meridian
- Risk category: Read (Low risk)

- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `symbol` | string | no | Optional symbol to scope code-anchored notes to (requires project_id). |
| `file_path` | string | yes |  |
| `project_id` | string | no | Include code-anchored notes (kind='code') for this project/path in the response. |
| `project_name` | string | no | Project name — an alternative to project_id; resolved to the id internally. project_id wins if both are given. |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_file_claims",
    "arguments": {
      "file_path": "<file_path>"
    }
  }
}
```

## Why get_file_claims is rated Low

This is a straightforward information retrieval operation that queries the state of file locks and claims. It has no side effects, creates no modifications, and cannot be misused to cause significant harm. Low severity reflects the informational nature of the output and limited blast radius if an AI agent calls it repeatedly or maliciously.

From the tool's own definition: "Tool is explicitly marked '[SUPPORT] Read-only' and described as 'show active claims on a file' with the function to 'check who owns a file before editing it'. It retrieves and displays lock/claim state and code-anchored notes without modifying any data."

Risk signals: Accepts file system path (file_path)

## Use case

AI agents call get_file_claims to retrieve information from Meridian without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Meridian:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_file_claims": {}
  }
}
```
