v0.4.0b4 — MCP Server
Pre-release
Pre-release
New in b4: MCP Server
ArbiterX now runs as a local MCP server — Claude Code queries the codebase map directly instead of reading raw files.
MCP Tools Exposed
arbiterx_query(query)— Search symbols (97% fewer tokens than reading files)arbiterx_overview()— Project structure + top symbolsarbiterx_gate(code, language)— Score code 0-100arbiterx_file_symbols(file_path)— List symbols in a file
Install
pip install arbiterx-gate[mcp]==0.4.0b4
arbiterx init && arbiterx map
/plugin marketplace add NeelPrime/arbiterx
/plugin install arbiterx@arbiterx-marketplaceHow It Works
Claude Code auto-starts the MCP server. When it needs to understand code, it calls arbiterx_query (600 tokens) instead of reading 50 files (200K tokens).
