relay · mcp for claude code

Your AI agent is
Relay shows you exactly why.

A latency profiler that reads your agent codebase, ranks every bottleneck by the time it costs, and applies the fix — all from a single Claude Code conversation.

Profiling that lives in your editor

[ capabilities · 06 ]
01

Runs inside Claude Code

No browser tab, no upload flow. Relay is an MCP server that lives in the editor you already work in.

02

Reads your actual code

AST analysis over your real .py source — not logs, not traces, not guesses. The true source of bottlenecks.

03

Ranked by time cost

Findings sorted by the milliseconds they cost, so you fix what matters instead of chasing micro-optimizations.

04

One-command fixes

Ask Claude Code to apply a fix and Relay patches the file in place, with a diff you approve first.

05

CI-ready engine

Wire the same engine into a GitHub Action and fail the build when a change regresses agent latency.

06

Your code stays yours

Analysis runs locally through the MCP server. Only usage metadata syncs — never your source.

Install to fix in under a minute

[ workflow ]
01
$add relay to ~/.claude/config

Add one config block

Drop the Relay MCP entry into your Claude Code config and paste your API key.

02
$audit this codebase for latency

Ask for an audit

Relay parses your code and returns every bottleneck, ranked by the time it costs.

03
$apply the fix for #01

Apply the fixes

Review the ranked findings, then let Relay patch the ones you approve, right in the editor.
