Minimal MCP server for HREVN tools backed by the live managed API.

HREVN MCP Server

Minimal MCP server for HREVN, backed by the live managed runtime at https://api.hrevn.com.

Why this exists

For Anthropic and later Codex, MCP is the cleanest way to expose HREVN as real tools rather than only as local helper scripts. This server stays thin on purpose:

• canonical semantics remain in the private HREVN core
• execution remains in the live HREVN managed runtime
• the MCP layer only exposes HREVN capabilities in a standard tool interface

Included tools

• baseline_check
• profile_validate
• generate_bundle
• verify_bundle

Environment

export HREVN_API_BASE_URL="https://api.hrevn.com"
export HREVN_API_KEY="replace-me"

Install

cd hrevn-mcp-server
pip install -e .

If you install into a virtual environment, make sure the same virtual environment is active when you launch Claude Code. Otherwise hrevn-mcp-server may not be on the PATH Claude Code uses.

Run

hrevn-mcp-server

The server uses MCP stdio transport.

Verify before opening Claude Code

hrevn-mcp-server --version
hrevn-mcp-server --list-tools
hrevn-mcp-server --self-test

The self-test runs a live baseline_check against the configured HREVN managed API.

If hrevn-mcp-server is not found, use the absolute executable path from the active environment, for example:

which hrevn-mcp-server

and place that path in your Claude Code MCP config instead of the bare command.

Claude Code MCP example

See:

• docs/CLAUDE_CODE_MCP_CONFIG.md
• examples/baseline_check_payload.json
• server.json

Recommended first test

Once Claude Code has this MCP server configured, ask it to call:

• baseline_check

with the payload in:

• examples/baseline_check_payload.json

That should return a real BaselineResult from the live HREVN managed API.

Design rule

This server must not reimplement HREVN truth locally. It should only expose stable MCP tools that call the managed API.

Registry readiness

This repo includes:

• server.json

as a machine-readable manifest describing the server, transport, environment, and exposed tools for registry and catalog use.

Current status

This is a minimal first MCP server aimed at Anthropic-first testing. It is intentionally thin, real, and compatible with the live managed API path already in production.
