The Graph-Native Intelligence Layer for Code.
Most developer tooling work still happens through a UI a human drives. Arbor MCP server moves it into the conversation instead. The Graph-Native Intelligence Layer for Code.
Simulated replay — the arbor commands and their output are real (tokio @ 178k LOC). Methodology: BENCHMARKS.md
The server publishes 5 tools. What each one is for:
Tier — ToolsOrientation — get_mapSurgical — list_entry_points · get_callers · get_callees · search_symbols · get_file_graph · get_node_detailBroad — get_logic_path · analyze_impact · find_path · get_knowledge_pathAgent-native — get_blast_radius · explain_symbol · audit_security · get_architecture_overview · batch_queryConfiguration is passed through the environment: GITHUB_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
@anandb71/arbor-cli on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Arbor's toolset — Tier, Orientation, Surgical and 2 more — is a fair guide to whether it matches your workflow. It is maintained by Anandb71; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
