Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed 2 days ago, and the latest version (0.10.0) reached the registry 2 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

Deploy durable AI agents with Omnara, an open-source managed-agent platform.
Codebase intelligence for AI coding agents: graph, git history, docs, decisions, code health.
Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.
Find code across thousands of repositories in milliseconds, with up to 50× fewer tokens. For you and your agents.
Self-hosted code search and code intelligence for GitLab, GitHub and Gitea, written in Rust. Every feature is open source under Apache-2.0, including SSO, SCIM, RBAC and audit logs. There is no paid tier, and there will not be one.
Quick install · Production install · Documentation · Query language · AI agents (MCP) · Architecture · Development
Agents connected over MCP read only the lines that answer their question, with up to 50× fewer tokens than cloning and grepping (token usage).
Sourcegull uses a trigram index of its own. After a push, only the changed paths are written to a delta shard, so new commits are searchable within seconds without rebuilding the repository's index. Small repositories are packed together into compound shards, which keeps instances with thousands of repositories fast. Revisions that are not indexed (any branch, tag or commit) are searched straight from git. Results stream as they are found.
How it compares with the alternatives on the same GitLab: Benchmark.
Every feature is in this repository under Apache-2.0. There is no enterprise edition, no licence key and no paid tier, and the project will not add one. That includes the features that other code search products usually sell separately:
Also included: literal, regexp, keyword (BM25) and structural search; notebooks; code ownership; saved searches and search contexts; a GraphQL API, the gull CLI and outbound webhooks; Grafana dashboards and documented alerts. See the documentation.
To try Sourcegull or run it for a small team on one host, download the Compose bundle of the latest release and start PostgreSQL and Sourcegull with the published image, ghcr.io/sourcegull/sourcegull (linux/amd64):
curl -fsSL https://github.com/sourcegull/sourcegull/releases/latest/download/sourcegull-compose.tar.gz | tar -xz
cd sourcegull-compose echo "POSTGRES_PASSWORD=$(openssl rand -hex 24)" > .env docker compose up -d
Open http://localhost:7080. The first user to sign up becomes the site admin. Add a GitLab, GitHub or Gitea connection under Site admin → Code host connections, and repositories start cloning and indexing.
docs/install.md is the install guide. For production, use one of these:
compose.production.yaml, one container per role), for one host: install.md → Production layout.Running either one is covered by the docs on upgrades (Compose, Helm), backups, monitoring and configuration as code.
/.api/mcp is a Model Context Protocol server. Coding agents search code, read files, find symbols, definitions and references, and read history (log, commits, compare, blame) with the caller's permissions, in output sized for a model's context. Connect an agent in the sidebar gives copy-paste setup for Claude Code, Cursor, VS Code, Codex, Gemini CLI, Zed, JetBrains and others, with a one-click token. For Claude Code:
claude mcp add --transport http sourcegull https://sourcegull.example.com/.api/mcp \
--header "Authorization: Bearer "
Tools and examples: docs/mcp.md.
One binary, sourcegull, runs in roles: web (UI, APIs, search fan-out), repo (git storage, index shards and search, partitioned across nodes), worker (background jobs) and blob (blob store); sourcegull supervise runs them all in one process. sourcegull executor runs sandboxed jobs in Docker or Kubernetes. PostgreSQL holds the data, job queues, leases and caches; there is no Redis. Each repo node indexes and searches its own repositories; web parses the query, applies permissions, fans it out to the nodes and merges the result streams. Details in docs/architecture.md.
Everything runs in Docker; nothing to install but Docker with Compose.
docker compose up -d # Postgres, Sourcegull built from this checkout, UI dev server
