### Description (declared)

# 🚀 Memgraph MCP Server

Memgraph MCP Server is a lightweight server implementation of the Model Context Protocol (MCP) designed to connect Memgraph with LLMs and different clients.

## 🔧 Tools

The default `server` implementation exposes the following seven tools over MCP.
(`memgraph-experimental` — see [Multi-Server Architecture](#multi-server-architecture) —
exposes a different, smaller set, documented there.)

### run_cypher_query(query: str)

Run any arbitrary Cypher query against the connected Memgraph database. Returns
one row per result, with each value in a **type-preserving** form: nodes,
relationships and paths come back as `_type`-tagged objects carrying their `id`,
`labels`/`type`, endpoints and `properties`; primitives, lists, maps, temporals
and points keep their shape. A single node looks like:

```json
{
  "n": {
    "_type": "node",
    "id": "<element_id>",
    "labels": ["Person"],
    "properties": { "name": "Alice" }
  }
}
```

Because rows are preserved, a query can mix graph entities with scalars — e.g.
`MATCH (n)-[e]->() RETURN n, count(e) AS out_deg` returns each node alongside its
count.

To get a **deduplicated, ready-to-render graph** (each node and relationship
once — useful for visualization), let Cypher do the dedup and return the two
lists directly:

```cypher
MATCH (n)-[r]->(m)
WITH collect(DISTINCT r) AS relationships, collect(DISTINCT n) + collect(DISTINCT m) AS ns
UNWIND ns AS nx
RETURN collect(DISTINCT nx) AS nodes, relationships
```

Each collected node and relationship comes back in the same typed form as above,
so the result is a compact graph payload without repeating shared nodes per row.

**Read-Only Mode:** By default, the server runs in read-only mode to prevent accidental data modifications. Write operations (CREATE, MERGE, DELETE, SET, DROP, REMOVE) are automatically blocked and will return an error. Set `MCP_READ_ONLY=false` to enable write operations.

Parameters:

- `query`: A valid Cypher query string.
