About this codebase
`repo` is a C++ cryptography and MPC codebase that consumes demo inputs (e.g., ECDSA/Schnorr key material and protocol parameters) and transforms them through core crypto primitives, MPC/protocol job orchestration, and ZK-related utilities into runnable demo binaries and testable artifacts (unit/integration tests and supporting libraries).
Written by gpt-5.4-nano from the index
380 files and 5,535 symbols in 9 modules, led by C++ (321 files) and Shell (7).
Code health
This codebase scores 7.8 out of 10 for code health, which we rate good. It also scores maintainability 9.1 and static performance 10.0 out of 10. The three are scored separately and never blended into one number. Risk is concentrated, as it usually is: 4 of 380 files are git hotspots, and they average 4.7 — which is where the fixes pay off most.

Nothing in the graph reaches them, across 75 files; every reader and agent pays to skip them.

Improve what Repowise can see
Add a test coverage report
Without one, Repowise cannot tell tested code from untested code, so every test-related action says “unknown”.
- line coverage
- Unknown, no report
Small effortReview the 65 proposed decisions
None is accepted yet, so nothing can drift from one and agents get no enforced guidance from them.

Use coinbase/cb-mpc in your agent
Point Claude Code, Cursor, Codex or VS Code at this repository. Your agent gets the index this page is built from: cited answers, callers, history and health for any file.
https://api.repowise.dev/mcp/coinbase/cb-mpcOne command, run anywhere. Adds the server to your local Claude Code config.
Docsclaude mcp add --transport http repowise https://api.repowise.dev/mcp/coinbase/cb-mpc \ --header "Authorization: Bearer rw_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
This repo is public, so anyone with a Repowise account and an API key can connect.
Try asking
- get_overview()
- get_answer("how is cb-mpc put together?")
- get_why("why is cb-mpc structured this way?")
Prefer local? pip install repowise && repowise init indexes your own checkout, no account needed.

Coinbase MPC Library This page is a map of the coinbase/cb-mpc repository, written primarily in C++, rebuilt from the source each time it is indexed. Repowise parses every symbol, computes a dependency graph, scores per-file code health from complexity, duplication, test coverage and churn, mines git history for hotspots and ownership, and lifts the architectural decisions into documentation you can read here or query through MCP.
The codebase has 380 files and 5,535 symbols in 9 modules, led by C++, Shell and Dockerfile. Code health is 7.8 out of 10, rated good.
