Which one, for what

Graphify B

Best for A person or team who wants a coding agent to query a structural map of a repository, with docs and papers folded in, before grepping.

Ahead on

  • Reliability, 58 against 25
  • Schema & documentation, 77 against 71
  • Agent ergonomics, 77 against 72
  • Payments & pricing, 60 against 15
  • Transparency & trust, 83 against 78

Also in its favour

  • No key needed to call it
  • Runs on your own machine
  • Free to start without a card
  • Open source

Watch for

Headless extraction sends docs to whichever cloud provider's key is set, Gemini first and Kimi in China second, unless GRAPHIFY_BACKEND is set

Sourcegraph MCP Server C

Best for A company that already runs Sourcegraph and wants agents to search and navigate many repositories with compiler-accurate definitions and references.

Ahead on

  • Security & auth, 76 against 66

Watch for

Enterprise plans only, from a $16,000 minimum annual contract through sales. A Cloud trial is by request and subject to eligibility

Verdicts

Graphify

Graphify parses code locally with tree-sitter, ships near-daily releases with a dated changelog, and keeps its ten MCP tools read-only and compact. The optional model step picks a cloud provider from whichever API key is set, and community naming can fall back to the claude CLI, so GRAPHIFY_BACKEND=none is needed to keep everything on the machine.

Sourcegraph MCP Server

Sixteen read-only tools search and navigate code across every repository an instance indexes, with OAuth limited to an mcp scope and repository permissions enforced on each call. Access needs an Enterprise contract, priced from $16,000 a year, and no request rate limits were found in the reviewed documentation.

Before you call either

Graphify

  1. Install graphifyy with two y's; other graphify* packages on PyPI are not the project's
  2. Set GRAPHIFY_BACKEND=none or use --code-only when no source or doc text may leave the machine
  3. Pass an absolute path to graph.json in the MCP config, and run graph_stats first to check the graph loaded
  4. Set GRAPHIFY_API_KEY before binding the HTTP server to 0.0.0.0; it only warns when no key is set
  5. Run 0.9.70 or later before indexing an untrusted repository, because earlier versions carry the Fortran file-read advisory

Sourcegraph MCP Server

  1. Connect to https://<instance>/.api/mcp for the nine core tools. Use /.api/mcp/all for go_to_definition, find_references, nls_search and compare_revisions
  2. Request only the mcp scope in OAuth. Any other scope on the MCP resource fails with invalid_scope
  3. Without OAuth, send Authorization: token <access token> and create the token with the mcp scope and an expiry
  4. Call list_repos first and name the repository in every code_finder task. It declines broad searches across repositories
  5. Read large files with startLine and endLine. Files over 128KB return only the first 200 lines

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
