MOST DANGEROUS TOOLS

High Risk

Execute · High farnsworth_browse This tool triggers an autonomous web browsing agent that performs actions on the internet to achieve arbitrary goals. Execute · High farnsworth_delegate This tool triggers autonomous agent execution across multiple specialist domains including code execution, reasoning, research, and creative tasks. Write · Medium farnsworth_project_transfer_knowledge This tool writes/copies knowledge artifacts from one project to another, modifying the destination project's knowledge base. Write · Low farnsworth_project_add_milestone This tool creates new milestone records within a project management system.

12 of Farnsworth's 20 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

HOW TO CONTROL FARNSWORTH

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

Rate limit write operations

{
  "farnsworth_project_transfer_knowledge": {
    "limits": [
      {
        "counter": "farnsworth_project_transfer_knowledge_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "farnsworth_list_exports": {
    "limits": [
      {
        "counter": "farnsworth_list_exports_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

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

Add these rules — paste them, or build them visually. Tune the limits to your setup.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

WRITE 10 tools

Write farnsworth_project_transfer_knowledge Transfer learnings and knowledge from one project to another. Uses LLM to identify transferable insights. Write farnsworth_evolve Provide feedback to help Farnsworth improve. Positive or negative feedback helps the system learn and adapt. Write farnsworth_project_achieve_milestone Mark a milestone as achieved. Write farnsworth_project_link Link two projects to enable knowledge transfer. Linked projects can share concepts and learnings. Write farnsworth_remember Store information in memory Write farnsworth_project_add_milestone Add a milestone to a project. Milestones track major project goals and deadlines. Write farnsworth_project_add_task Add a task to a project. Tasks can have dependencies on other tasks. Write farnsworth_project_complete_task Mark a task as completed. This will automatically unblock dependent tasks. Write farnsworth_project_create Create a new project to track. Projects can have tasks, milestones, and can be linked to other projects for kn Write farnsworth_project_update Update an existing project

FAQ

How do I prevent bulk modifications through Farnsworth? +

The Farnsworth server has 10 write tools including farnsworth_project_transfer_knowledge, farnsworth_evolve, farnsworth_project_achieve_milestone. 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 Farnsworth.

How many tools does the Farnsworth MCP server expose? +

20 tools across 3 categories: Financial, Read, Write. 8 are read-only. 12 can modify, create, or delete data.

How do I enforce a policy on Farnsworth? +

Register the Farnsworth 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 Farnsworth tool call.

Deterministic rules across all 20 Farnsworth tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
