v2.1.0 — Agent-Native MCP

🔧 New: 10 MCP Tools

This release introduces six new surgical tools for precise graph traversal to complement the existing broad-analysis suite.

Surgical (New in v2.1.0)

• list_entry_points — Lists all production entry points: main, HTTP handlers, webhooks, background jobs, and CLI commands.
• get_callers — Identifies every node that calls a specific symbol.
• get_callees — Identifies every node called by a specific symbol.
• search_symbols — Performs a fuzzy search across all symbol names.
• get_file_graph — Maps all nodes and intra-file edges for a specific file path.
• get_node_detail — Provides full metadata for a node via ID or name.

Broad (Unchanged)

get_logic_path · analyze_impact · find_path · get_knowledge_path

🔗 New: Standard Response Envelope

All 10 tools now utilize a consistent return shape with built-in agent chaining hints to streamline workflows:

{
  "ok": true,
  "tool": "get_callers",
  "arbor_version": "2.1.0",
  "data": { ... },
  "meta": {
    "node_count": 4,
    "suggested_next_tool": "analyze_impact",
    "suggested_next_args": { "node_id": "arbor_core::parser_v2::parse_file" }
  }
}
