### Description (declared)

# ohwise-mcp

[![PyPI version](https://img.shields.io/pypi/v/ohwise-mcp.svg)](https://pypi.org/project/ohwise-mcp/)

**MCP server connecting AI coding agents to graph-native code context and multi-agent pipelines.**

`ohwise-mcp` implements the [Model Context Protocol](https://modelcontextprotocol.io/) so that any MCP-compatible AI agent (Claude Code, Claude Desktop, and others) can:

- Build and query **knowledge graphs** from code repositories via [codebase2graph](https://github.com/jw-open/codebase2graph)
- Build and query **knowledge graphs** from documents via [docs2graph](https://github.com/jw-open/docs2graph)
- Rank the most relevant nodes for any query using **Personalized PageRank**
- Trigger and poll **OhWise Studio pipelines** for multi-agent task execution

**Pure Python. No LLM dependency for graph tools. Bring your own model.**

---

## Quick start

```bash
pip install ohwise-mcp[all]
```

### Add to Claude Code

```bash
claude mcp add ohwise -- ohwise-mcp
```

Or manually in your Claude Code config (`~/.claude.json` or `.mcp.json`):

```json
{
  "mcpServers": {
    "ohwise": {
      "command": "ohwise-mcp",
      "env": {
        "OHWISE_URL": "https://your-ohwise-instance.com",
        "OHWISE_TOKEN": "your-token-here"
      }
    }
  }
}
```

> `OHWISE_URL` and `OHWISE_TOKEN` are only required for Studio pipeline tools. Graph tools work offline without them.

## Tools

### Code graph tools

| Tool | Description |
|------|-------------|
| `build_code_graph(repo_path, graph_type)` | Extract a knowledge graph from a code repository |
