9Router × CodeGraph

[pcldev]

TL;DR — 9Router already cuts 20–40% of tokens by compressing what the agent sends. CodeGraph cuts tokens at the other end — by reducing how often the agent has to grep / read / explore in the first place. They stack, and they already work together today with zero integration. Worth documenting the combo (and maybe a nod in Acknowledgments)?

Hey @decolua and the 9Router community,

9Router's whole promise is simple: never stop coding, stop bleeding tokens. RTK nails this after the agent decides to act — it compresses the git diff, grep, ls, tree output before it ever reaches the model. Beautiful.

But there's a second leak RTK can't reach from the proxy layer: the discovery phase. Before an agent edits a single line, it burns dozens of tool calls just figuring out where the relevant code lives — find, ls, grep, Read, repeat. On a large repo, that's where most of the budget quietly disappears.

That's the exact gap [CodeGraph](https://github.com/colbymchenry/codegraph) fills. It's a 100% local MCP server that pre-indexes your codebase into a queryable knowledge graph, so the agent asks the map instead of scanning the files.

Their published benchmarks (re-validated on Opus 4.8, June 2026):

• ~47% fewer tokens
• ~58% fewer tool calls
• ~16% cheaper per task
• …with near-zero file reads on real-world repos.

Here's the part I like most: there's nothing to build. The two tools live at different layers and compose out of the box today —

• Point your CLI tool at 9Router for the model → RTK compresses each tool output.
• Add CodeGraph as an MCP server → far fewer tool outputs to compress in the first place.

RTK shrinks each trip. CodeGraph removes trips. The savings compound. Same audience, same mission, two different leaks plugged.

So the ask is small:

1. Would a short "Recommended companion: CodeGraph" section in the docs be welcome? Happy to open the PR.
2. Worth a spot in Acknowledgments next to RTK and Caveman? Same family of token-savers.

And for everyone reading — is anyone already running this combo? Curious what real numbers you're seeing. 👇

Actually good idea agent use few tools calls and graph instead making multi calls

Actually I created pr even to add support for mcp #1918
