### Description (declared)

# HugeGraph MCP

[中文文档](README.zh-CN.md)

HugeGraph MCP is a safe, controlled Model Context Protocol adapter for HugeGraph Server. It exposes stable structured tools, centralizes configuration and permission checks, and persists immutable write plans and outcomes.

**Requires HugeGraph Server >= 1.7.0.** The default graph path is `DEFAULT/hugegraph` and uses graphspace-scoped APIs unavailable in older releases.

## Quick Start

Installing a published package does not require cloning this repository. The
commands below target `1.7.1` on PyPI; until it is published, use the
[developer setup](#developer-notes). See the [release workflow](docs/releasing.md).

Install [uv](https://docs.astral.sh/uv/getting-started/installation/), then start the server in read-only mode:

```bash
export HUGEGRAPH_URL=http://hugegraph.example.com:8080
export HUGEGRAPH_GRAPH_PATH=DEFAULT/hugegraph
export HUGEGRAPH_USER=admin
export HUGEGRAPH_PASSWORD=admin
export HUGEGRAPH_MCP_READONLY=true

uvx hugegraph-mcp@1.7.1
```

The process speaks MCP JSON-RPC on stdout. Keep `HUGEGRAPH_MCP_READONLY=true` unless controlled writes are required. The default toolset is `v2_core`; set `HUGEGRAPH_MCP_TOOLSET=v1` before startup only for the legacy 10-tool contract.

For MCP clients that accept JSON server configuration:

```json
{
  "mcpServers": {
    "hugegraph": {
      "command": "uvx",
      "args": ["hugegraph-mcp@1.7.1"],
      "env": {
        "HUGEGRAPH_URL": "http://hugegraph.example.com:8080",
        "HUGEGRAPH_GRAPH_PATH": "DEFAULT/hugegraph",
        "HUGEGRAPH_USER": "admin",
        "HUGEGRAPH_PASSWORD": "admin",
        "HUGEGRAPH_MCP_READONLY": "true"
      }
    }
  }
}
```

## Developer Notes

To try both packages from the same checkout, run from the repository root:

```bash
uvx --no-config --no-cache --with ./hugegraph-python-client --from ./hugegraph-mcp hugegraph-mcp
```

From the root of the PR checkout, install uv, then create an isolated environment and install both packages fr…
