HREVN CLI runner for Claude Code and Anthropic-facing workflows.

HREVN for Claude Code - Verifiable Workflow State via MCP and Skills

This repo is the Anthropic-facing HREVN surface for Claude Code: skills, a local runner, and an MCP path for resumable workflows, tamper-evident receipts, and audit-ready traceability against the live HREVN managed runtime.

Why HREVN

AI agents and multi-step workflows fail in ambiguous ways. When a sequence is interrupted, neither the user nor the system can always determine with certainty what completed, what failed mid-execution, and where work can safely resume. Without a verifiable record, context is reconstructed from memory or chat history, wasting tokens, repeating work, and leaving no reliable trail.

HREVN adds a structured evidence layer: baseline checks before consequential steps, tamper-evident receipts after execution, and manifests that allow workflows to continue from the last verified point rather than restarting from scratch.

For teams operating in regulated or high-stakes environments, HREVN also supports evidentiary discipline: structured records of what ran, under what authority, and when it stopped. This is particularly relevant for AI systems that may fall within EU regulatory timelines in 2026 and beyond. HREVN does not make a system legally compliant, but it provides structured, verifiable evidence that compliance, audit, and governance processes can use.

In Anthropic-facing workflows, HREVN extends the skill layer with structured records of what ran, under what authority, and where execution can safely resume through the runner bridge to the managed runtime.

What it is

• an Anthropic-facing skill repo
• a thin public surface
• a local runner bridge to https://api.hrevn.com
• an MCP-ready path for Claude Code tool use

What it is not yet

• not a native remote-skill marketplace package
• not yet a polished end-user MCP distribution
• not the private HREVN runtime
• not the private commercial toolkit

Skill chain

1. hrevn-baseline-check
2. hrevn-sign-on-complete
3. hrevn-verify-bundle

Quick Start

pipx install hrevn-anthropic-runner
export HREVN_API_KEY="<issued-alpha-key>"
hrevn-anthropic health-check
hrevn-anthropic self-test
hrevn-anthropic baseline

If you prefer the repo checkout instead, you can still do:

git clone https://github.com/ai-human-andalusia/hrevn-surface-anthropic
cd hrevn-surface-anthropic
pipx install .

If pipx is not available, a local fallback is:

python3 -m pip install .

The installable command should return a real BaselineResult JSON once auth is set correctly.

For the MCP-first and guided alpha path, see:

• docs/ANTHROPIC_ALPHA_TESTING.md
• docs/MCP_USAGE.md

Alpha keys are issued out-of-band for testing rather than embedded in the public repo.

Optional MCP path

If you want Claude Code to discover HREVN as MCP tools rather than only through skill guidance plus a local runner, use the companion MCP server at:

• https://github.com/ai-human-andalusia/hrevn-mcp-server

See:

• docs/MCP_USAGE.md
• docs/claude_code_mcp_config.example.json

Test in Claude Code

1. Open Claude Code in this repository.
2. Make sure HREVN_API_KEY is exported in the shell environment Claude Code will use.
3. First verify the runner directly:

hrevn-anthropic self-test
hrevn-anthropic baseline

4. Then ask Claude Code:

Run a baseline check on examples/baseline_check_request.json

The expected path is:

skill instructions -> local runner -> https://api.hrevn.com

What is already proven in this repo

• the local runner can call the live managed API
• the baseline-check example returns a real BaselineResult
• the current path is usable today without waiting for MCP
• the Anthropic surface now has a documented MCP upgrade path for the same backend

Included

• .claude/skills/...
• docs/MANAGED_API_USAGE.md
• pyproject.toml
• scripts/hrevn_anthropic_runner.py
• src/hrevn_anthropic_runner/...
• examples/baseline_check_request.json

Managed Runtime Bridge

The live managed endpoint is:

• https://api.hrevn.com

Current path:

• skill guidance now
• local runner bridge now
• MCP available as the next bridge when Claude Code is configured for it

Current status

This is a public Anthropic surface candidate with a real testing path today. It is intentionally honest about the current runner-first path while also exposing an MCP route for Anthropic-first testing.

Rule

The skills guide behavior, but the runtime truth stays in the managed API and private HREVN core. The skill itself does not natively perform remote HTTPS on its own.
