Kodit

A code and document intelligence server that indexes Git repositories and provides search through MCP and REST APIs.

AI coding assistants work better when they have access to real examples from your codebase. Kodit indexes your repositories, splits source files into searchable snippets, and serves them to any MCP-compatible assistant. When your assistant needs to write new code, it queries Kodit first and gets back relevant, up-to-date examples drawn from your own projects.

Kodit also handles documents. PDFs, Word files, PowerPoint decks, and spreadsheets are rasterized and indexed so you can search across both code and documentation in one place.

What you get:

• Multiple search strategies including BM25 keyword search, semantic vector search, regex grep, and visual document search, each exposed as a separate MCP tool so your assistant picks the right approach for each query
• MCP server that works with Claude Code, Cursor, Cline, Kilo Code, and any other MCP-compatible assistant
• REST API for programmatic access to search, repositories, enrichments, and indexing status
• AI enrichments (optional) including architecture docs, API docs, database schema detection, cookbook examples, and commit summaries, all generated by an LLM
• Document intelligence with visual search across PDF pages, Office documents, and images using multimodal embeddings
• No external dependencies required for basic operation, with a built-in embedding model and SQLite storage

Quickstart

Docker (recommended)

docker run -p 8080:8080 registry.helix.ml/helix/kodit:latest

This starts Kodit with SQLite storage and a built-in embedding model. No API keys needed.

Pre-built binaries

Download a binary from the releases page, then:

chmod +x kodit
./kodit serve

Verify it works

Open the interactive API docs at http://localhost:8080/docs.

Or index a small repository and run a search:

# Index a repository
curl http://localhost:8080/api/v1/repositories \
  -X POST -H "Content-Type: application/json" \
  -d '{
    "data": {
      "type": "repository",
      "attributes": {
        "remote_uri": "https://gist.github.com/philwinder/7aa38185e20433c04c533f2b28f4e217.git"
      }
    }
  }'

# Check indexing progress
curl http://localhost:8080/api/v1/repositories/1/status

# Search (once indexing is complete)
curl http://localhost:8080/api/v1/search \
  -X POST -H "Content-Type: application/json" \
  -d '{
    "data": {
      "type": "search",
      "attributes": {
        "keywords": ["orders"],
        "text": "code to get all orders"
      }
    }
  }'

Connecting to AI Assistants

Kodit exposes an MCP endpoint at /mcp. Connect your assistant to start using Kodit as a code search tool.

Claude Code

claude mcp add --transport http kodit http://localhost:8080/mcp

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "kodit": {
      "url": "http://localhost:8080/mcp"
    }
  }
}

Cline

Add to the MCP Servers configuration (Remote Servers tab):

{
  "mcpServers": {
    "kodit": {
      "autoApprove": [],
      "disabled": false,
      "timeout": 60,
      "type": "streamableHttp",
      "url": "http://localhost:8080/mcp"
    }
  }
}

Kilo Code

Add to the MCP configuration (Edit Project/Global MCP):

{
  "mcpServers": {
    "kodit": {
      "type": "streamable-http",
      "url": "http://localhost:8080/mcp",
      "alwaysAllow": [],
      "disabled": false
    }
  }
}

Replace http://localhost:8080 with your server URL if running remotely.

Encouraging assistants to use Kodit

Some assistants may not call Kodit tools automatically. Add this to your project rules or system prompt to enforce usage:

For every request that involves writing or modifying code, the assistant's first
action must be to call the kodit search MCP tools. Only produce or edit code after
the tool call returns results.

In Cursor, save this as .cursor/rules/kodit.mdc with alwaysApply: true frontmatter.

MCP Tools

Kodit exposes these tools to connected AI assistants:

The enrichment tools (architecture_docs, api_docs, database_schema, cookbook, wiki, commit_description) require an LLM provider to be configured. See Enrichment Providers under Configuration Reference.

Go Library

Kodit can be embedded directly as a Go library. This is how Helix integrates Kodit into its platform.

import "github.com/helixml/kodit"

client, err := kodit.New(
    kodit.WithSQLite(".kodit/data.db"),
)
if err != nil {
    log.Fatal(err)
}
defer client.Close()

// Index a repository
repo, err := client.Repositories.Add(ctx, &service.RepositoryAddParams{
    URL: "https://github.com/kubernetes/kubernetes",
})

// Search
results, err := client.Search.Query(ctx, "create a deployment",
    service.WithLimit(10),
)

for _, snippet := range results.Snippets() {
    fmt.Println(snippet.Path(), snippet.Name())
}

Go HTTP client

A generated HTTP client is available for calling a remote Kodit server from Go:

go get github.com/helixml/kodit/clients/go

import koditclient "github.com/helixml/kodit/clients/go"

client, err := koditclient.NewClient("https://kodit.example.com")

// List repositories
resp, err := client.GetApiV1Repositories(ctx)

// Search
resp, err := client.PostApiV1SearchMulti(ctx, koditclient.PostApiV1SearchMultiJSONRequestBody{
    TextQuery: "create a deployment",
    TopK:      10,
})

Types are auto-generated from the OpenAPI spec. See the interactive API docs at /docs for the full endpoint list.

Production Deployment

For production use, deploy with PostgreSQL (VectorChord) for scalable vector search and a dedicated LLM provider for enrichments.

Authentication

Set the API_KEYS environment variable to a comma-separated list of keys. Write endpoints (creating repositories, triggering syncs) require a valid key in the Authorization: Bearer <key> header. Search endpoints are open by default.

Configuration Reference

Configuration is done through environment variables. You can also use a .env file:

kodit serve --env-file .env

Server

Embedding Provider

These configure an external embedding model. If unset, Kodit uses its built-in model.

Vision Embedding Provider

These configure a remote service for image and text vision embeddings. If unset, Kodit uses its built-in SigLIP2 model.

Enrichment Providers

These configure an LLM for generating architecture docs, API docs, database schemas, cookbooks, commit summaries, and wiki pages. Without this, Kodit indexes and searches code but does not generate any AI documentation.

Enrichment is typically the slowest part of indexing because each enrichment requires a round-trip to the LLM provider. Increase NUM_PARALLEL_TASKS to speed things up, but respect your provider's rate limits. Start low and increase over time.

Provider examples:

# OpenAI
ENRICHMENT_ENDPOINT_BASE_URL=https://api.openai.com/v1
ENRICHMENT_ENDPOINT_MODEL=gpt-4o-mini
ENRICHMENT_ENDPOINT_API_KEY=sk-proj-xxxx

# Ollama (local)
ENRICHMENT_ENDPOINT_BASE_URL=http://localhost:11434
ENRICHMENT_ENDPOINT_MODEL=ollama/qwen3:1.7b

# Helix (private cloud)
ENRICHMENT_ENDPOINT_BASE_URL=https://app.helix.ml/v1
ENRICHMENT_ENDPOINT_MODEL=Qwen/Qwen3-8B
ENRICHMENT_ENDPOINT_API_KEY=your-helix-key

Periodic Sync

Chunking

REST API

The full API is documented interactively at /docs on a running Kodit instance. The OpenAPI 3.0 specification is available at /docs/openapi.json.

Key endpoints:

All write endpoints require an Authorization: Bearer <key> header when API_KEYS is set.

How Indexing Works

When you add a repository, Kodit runs a pipeline:

1. Clone the Git repository to local storage
2. Scan commits, branches, and tags to extract metadata
3. Extract snippets by splitting source files into overlapping text chunks
4. Build search indexes with BM25 (keyword) and vector embeddings (semantic)
5. Generate enrichments (if an LLM provider is configured): architecture docs, API docs, database schemas, cookbook examples, commit summaries, and wiki pages

Kodit tracks which files have changed between syncs and only reprocesses modified content. Repositories sync automatically on a configurable interval (default: every 30 minutes).

Supported sources

Kodit indexes any Git repository accessible via HTTPS, SSH, or the Git protocol. This includes GitHub, GitLab, Bitbucket, Azure DevOps, and self-hosted servers.

Private repositories

Private repositories are supported through personal access tokens or SSH keys:

# HTTPS with token
https://username:token@github.com/username/repo.git

# SSH (ensure your SSH key is configured)
git@github.com:username/repo.git

Privacy

Kodit respects .gitignore and .noindex files. Files matching these patterns are excluded from indexing.

Storage Backends

SQLite (default)

No configuration needed. Kodit creates a SQLite database in the data directory with FTS5 for keyword search and in-process vector storage. Good for single-user and small-team deployments.

PostgreSQL with VectorChord

For larger deployments, use PostgreSQL with the VectorChord extension. This provides scalable vector search and concurrent access. Set the DB_URL environment variable to your connection string.

The recommended Docker image is tensorchord/vchord-suite:pg17-20250601, which bundles PostgreSQL 17 with VectorChord, vchord_bm25, and pg_tokenizer.

Building from Source

git clone https://github.com/helixml/kodit.git
cd kodit
make tools          # Install development tools
make download-model # Download the built-in embedding model
make build          # Build the binary
./bin/kodit version
./bin/kodit serve

Run the tests:

make test                         # All tests
make test PKG=./internal/foo/...  # Specific package
make check                        # Format, vet, lint, and test

Troubleshooting

MCP connection error after restart: If you see No valid session ID provided after restarting the Kodit server, reload the MCP client in your assistant. MCP sessions do not survive server restarts.

No search results: Check that indexing has completed by calling GET /api/v1/repositories/{id}/status. If status shows errors, check the server logs with LOG_LEVEL=DEBUG.

Enrichments not generating: Enrichments require an LLM provider. Check that ENRICHMENT_ENDPOINT_BASE_URL and ENRICHMENT_ENDPOINT_MODEL are set. Without these, Kodit indexes and searches code but does not generate AI documentation.

Telemetry

Kodit collects limited anonymous telemetry (usage metadata only, no user data) to guide development. Disable it with:

DISABLE_TELEMETRY=true

Commercial Support

Helix provides a managed platform built on Kodit with additional features including a management UI, repository browsing, team collaboration, and hosted infrastructure. For commercial support or enterprise integration, contact founders@helix.ml.
