RepoRelayCode context for LLMs

Self-hosted, MCP-native code context engine.
Index any number of Git repos — from any host — and make them queryable by your LLM.

Why RepoRelay?

GitHub

📂

Unlimited Repositories

Register repos from any Git host — GitHub, GitLab, Bitbucket, Azure DevOps, on-premise, or local paths. Each independently indexed and queryable.

🔍

Hybrid Search

BM25 full-text (ParadeDB) + vector similarity (pgvector), fused via Reciprocal Rank Fusion in a single query. Not git grep — deep semantic search.

🌳

Deep Code Understanding

tree-sitter parsing extracts symbols, imports, signatures, and doc comments across TypeScript, JavaScript, Python, Go, Java, Kotlin, Rust, C, C++ — plus a custom Markdown parser.

🏷️

Versioned Snapshots

Every branch and tag is indexed independently. Query a specific version, or use semver ranges like ^1.2, ~3.0, or 2.x — RepoRelay resolves them automatically.

🤖

MCP-Native

7 tools, 2 resources, 3 prompts — works with Claude Desktop, Cursor, Windsurf, OpenCode, or any MCP host.

🔐

Full-Index + SHA-256 Dedup

Every ref indexes all files via git ls-tree. SHA-256 content addressing skips unchanged files — fast, correct, order-independent.

📦

Self-Hosted

Your code stays on your infrastructure. Postgres is the only runtime dependency. Private repos authenticate via env-var tokens.

🌐

Language Auto-Detection

The MCP proxy detects your project's languages from manifest files and automatically filters results to relevant repos.

Symbol-Aware Chunking

Intelligent splitting that respects function boundaries with overlap windows — never cuts a symbol in half.
