Current APIs, real usage, version diffs — compact, cited answers at a fraction of the tokens.
127,134 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.
agents: add the MCP endpoint · private repos: create a free workspace
indexing continuously — latest: github.com/anthropics/anthropic-sdk-python@v1.13.0 · 167h ago
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.
