Faramesh Core MCP Server

<div align="center"> <img src="README-LOGO.png" alt="Faramesh" width="480" />

Every agent tool call is a policy decision.

Declare permissions in governance.fms. A local daemon permits, defers, or denies each tool call before it runs. Decisions are hash-chained in a WAL. No SDK lock-in. No cloud required.

Works with the agent stack you already have

LangGraph · LangChain · CrewAI · OpenAI Agents · Claude Agents SDK · Claude Code · Cursor · MCP · AutoGen · AG2 · LlamaIndex · Pydantic AI · Bedrock · Semantic Kernel

13 frameworks today. SDK shim, MCP proxy, HTTP proxy, or A2A. Pick the tier that matches the agent. Framework guides →

What you get

• Deterministic decisions. Pure functions over policy and the action payload. No LLM in the decision path.
• Non-bypassable enforcement. Local daemon. Every tool call goes through it. No SDK to forget to wrap.
• Identity-bound. SPIFFE SVIDs, OIDC, or cloud workload identity. Credentials brokered at the call site.
• Tamper-evident audit. Decision Provenance Records, hash-chained WAL, optional KMS signing.

A policy

agent "support-bot" {
  default deny

  rules {
    permit crm/customers/read
    permit crm/tickets/create
    permit email/send             if domain == "@yourcompany.com"
    defer  email/send             if domain != "@yourcompany.com"
    defer  billing/cancel_subscription
    deny   billing/delete_account
  }

  rate_limit "email/send": 50 per hour

  budget daily {
    max       $20
    on_exceed defer
  }
}

External emails go to a human. Cancellations require a click. Deletion is impossible without editing the policy. Daily spend ceiling. Every decision lands in a verifiable log.

How Faramesh compares

Faramesh is the local enforcement daemon for tool-call decisions. It's narrower than full-stack agent platforms (Microsoft AGT) and operates outside the model output evaluation layer (Galileo Agent Control). Detailed comparison →
