MOST DANGEROUS TOOLS

High Risk

The most dangerous Allen Brain API MCP Server tools

Execute · High execute_rma_query This tool executes arbitrary RMA queries against an external API. Write · Low download_svg This tool retrieves data from the Allen Brain API and writes it to a local file.

2 of Allen Brain API MCP Server's 26 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Allen Brain API MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and Allen Brain API MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "download_svg": {
    "limits": [
      {
        "counter": "download_svg_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "download_annotation_volume": {
    "limits": [
      {
        "counter": "download_annotation_volume_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

FAQ

Questions about Allen Brain API MCP Server

How do I prevent bulk modifications through Allen Brain API MCP Server? +

The Allen Brain API MCP Server server has 1 write tools including download_svg. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Allen Brain API MCP Server.

How many tools does the Allen Brain API MCP Server MCP server expose? +

26 tools across 2 categories: Execute, Read. 24 are read-only. 2 can modify, create, or delete data.

How do I enforce a policy on Allen Brain API MCP Server? +

Register the Allen Brain API MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Allen Brain API MCP Server tool call.

Deterministic rules across all 26 Allen Brain API MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
