THE VIBE CODING NERVOUS SYSTEM

The world's public codebase,
available to your AI agents for free

Current APIs, real usage, version diffs — compact, cited answers at a fraction of the tokens.
126,377 repos as continuously-fresh code graphs over MCP. And it's not just public code: index your own repos and your agents get the same grounded understanding of your system — connected to the ecosystem it depends on.

already indexed? you land on its graph — new repos index in seconds, cached for everyone

agents: add the MCP endpoint  ·  private repos: create a free workspace

126,377 repos 288,556,792 symbols 983,918,063 edges 226,259 cross-repo links

Plug your own code into the nervous system

A free private workspace indexes your repos the same way: your agents can verify your APIs, trace calls across your repos, see the blast radius of a change before making it, and hop straight into the source of the open-source libraries you depend on — one connected graph, private to you, served over your own MCP endpoint.

What your agent sees computed facts from the live graph — not generated prose

1. Interface tempopb.PusherServer — modules/distributor · 4 implementers
2. Method Forwarder.ForwardTraces — modules/distributor/forwarder · "queues batches for the ingester"
3. Method distributor.PushTraces — called by 12 · calls 9

MCP — one endpoint, every graph

$ claude mcp add --transport http codehub https://codehub.bot/mcp

search · symbol_context · callers · implementers · impact · load_source · datastores — over any graph on this page.

Fetch — the from_pretrained() of code graphs

$ otcore fetch github.com/google/uuid@v1.6.0
$ otcore search uuid.db "parse a uuid from string"

7–50MB artifacts, offline-capable, hash-verified. sqlite, postgres and ladybug backends.

Your code, the same treatment.

All your repos in one private graph — cross-repo calls and blast radius between your services, your own MCP URL, re-indexed on every push. GitHub and GitLab.

GitHub

hosts the code — you still read it file by file.

HuggingFace

the registry for models, not for code context.

deepwiki

generated prose about repos. Humans only.

CodeHub

the graph of every repo@version — computed facts, blast radius, symbol permalinks, and an MCP endpoint for agents.
