Docs · MCP tools

The graph, as toolsyour agent calls.

Ten tools over the graph built from your repository, so any MCP client reads it natively instead of grepping.

Run the server

The server ships with the CLI and reads the graph.json that /graphify . produced (default graphify-out/graph.json). It speaks stdio by default (the right mode for a single assistant) or Streamable HTTP when several assistants or teammates should share one graph. The HTTP transport can require a key via --api-key (or the GRAPHIFY_API_KEY env var).

terminal

# stdio (default), one assistant, one graph:
$ python -m graphify.serve graphify-out/graph.json

# shared HTTP, one server, many clients:
$ python -m graphify.serve graphify-out/graph.json --transport http --port 8080

# also available as a console script:
$ graphify-mcp graphify-out/graph.json

Connect a client

Most assistants pick this up automatically: graphify install wires the server into the assistants it detects. To register it by hand in Claude Code, add this to .mcp.json in your project root; other MCP clients take the same command in their own config format.

.mcp.json

{
  "mcpServers": {
    "graphify": {
      "command": "python",
      "args": ["-m", "graphify.serve", "graphify-out/graph.json"]
    }
  }
}

Every tool below also accepts an optional project_path parameter (an absolute path to another project containing graphify-out/graph.json), so one running server can answer for a whole workspace of repos. Omit it and the server answers against the graph it was started with.

Query & traverse

The core four: ask a question, inspect a node, walk its neighbors, or trace the path between two concepts. Results come back as text context with file:line citations, every edge tagged EXTRACTED, INFERRED, or AMBIGUOUS.

query_graph

Search the graph for a natural-language question using BFS or DFS traversal. Returns the relevant nodes and edges as text context, the same output graphify query prints.

questionrequired: Natural-language question or keyword search.
modedefault bfs: bfs for broad context, dfs to trace a specific path.
depthdefault 3: Traversal depth (1–6).
token_budgetdefault 2000: Cap on output tokens.
context_filteroptional: Explicit edge-context filter, e.g. ["call", "field"].

get_node

Full details for one node, looked up by label or ID: what it is, where it lives, its community, and its edges.

labelrequired: Node label or ID to look up.

get_neighbors

All direct neighbors of a node, with edge details: one hop out in every direction.

labelrequired: Node label or ID.
relation_filteroptional: Only edges of this relation type.

shortest_path

The shortest path between two concepts in the graph: how two pieces of the codebase connect, hop by hop.

sourcerequired: Source concept label or keyword.
targetrequired: Target concept label or keyword.
max_hopsdefault 8: Maximum hops to consider.

Structure & overview

For orientation: the graph's communities, its most-connected nodes, and summary statistics: the "show me the shape of this codebase" tools an agent calls first in an unfamiliar repo.

get_community

All nodes in one community (the clusters the graph is organized into), by community ID.

community_idrequired: Community ID, 0-indexed by size.

god_nodes

The most-connected nodes in the graph: the core abstractions everything else hangs off.

top_ndefault 10: How many nodes to return.

graph_stats

Summary statistics: node count, edge count, communities, and the EXTRACTED / INFERRED / AMBIGUOUS confidence breakdown.

no parameters

Pull requests

The same graph-impact analysis behind graphify prs, exposed to agents: which open PRs touch what, and in which order to review them.

list_prs

Open GitHub PRs with CI status, review state, and graph impact: which communities each PR touches and its blast radius. Useful before starting work, to check if a PR already covers the area.

baseoptional: Base branch to filter by (auto-detected if omitted).
repooptional: owner/repo; defaults to the current repository.

get_pr_impact

Detailed graph impact for one PR: the files it changes, the communities affected, and how many nodes are touched, for assessing merge risk or overlap with current work.

pr_numberrequired: The PR number to analyse.
repooptional: owner/repo; defaults to the current repository.

triage_prs

All actionable open PRs (right base branch, not stale) with full graph-impact data, so the agent can reason about review priority, merge order, and conflict risk.

baseoptional: Base branch to filter by (auto-detected if omitted).
repooptional: owner/repo; defaults to the current repository.

Resources

Alongside the tools, the server publishes MCP resources, read-only documents a client can pull into context: the full GRAPH_REPORT.md, graph stats, god nodes, surprising cross-community connections, the confidence audit, and suggested questions for the codebase.

Not the docs MCP server

This page covers the graph MCP server, the one the CLI runs locally over your own repo. Graphify also hosts a separate docs MCP server with a single tool, search_graphify_docs, for searching this documentation from your editor. Different server, different job.
