Javelin Guardrails Mcp Server
Wire Javelin standalone guardrails into Claude Code or Cursor so agent prompts and outputs get policy checks before they hit users or production.
Overview
Javelin Guardrails MCP Server is a Ship-phase MCP server that connects coding agents to Javelin Standalone Guardrails over streamable HTTP with API-key authentication.
What is this MCP server?
- Remote MCP over streamable HTTP at the published Javelin endpoint
- Requires x-javelin-apikey header for authenticated guardrail calls
- Javelin Standalone Guardrails as MCP-exposed capabilities
- Fits agents that need centralized safety policy without custom middleware
- Server schema version 1.0.0
- One required secret header: x-javelin-apikey
- Transport: streamable-http remote MCP endpoint
What problem does it solve?
Agent replies can violate policy or leak sensitive patterns, and rebuilding guardrails in every project is slow and inconsistent.
Who is it for?
Indie builders running MCP agents who already have or plan a Javelin API key and want centralized LLM guardrails.
Skip if: Teams without a Javelin account or anyone who only needs static prompt instructions with no policy service.
What do I get? / Deliverables
After you register the remote MCP server and API key, your agent can call Javelin guardrails as tools during development and pre-launch hardening.
- MCP-configured connection to Javelin Standalone Guardrails
- Agent-callable guardrail tooling during development
- Consistent policy layer across MCP-compatible agents

How it compares
MCP integration to a guardrails API, not a local lint skill or generic code-security scanner.
