Codebase context · delivered via MCP

Lower cost. Higher quality.
Same agent.

Code Lexica is a persistent context layer for your codebase, delivered as an MCP server. Plug it into Claude Code, Cursor, or Copilot and your agent stops paying to re-discover your architecture on every run.

  • up to 40% fewer tokens per agent run on Opus 4.8 (SWE-Bench Pro)
  • Higher first-pass pass rates, same model
  • Works with Claude Code, Cursor, Copilot, Codex, Gemini CLI — no agent swap
  • One MCP endpoint. 15-minute setup. No workflow changes.
  • Evidence-backed responses — every answer traces to source

The cost problem

The agentic free lunch is over.

Anthropic moved programmatic Claude usage off subscription pools onto full API rates. GitHub Copilot moved agent mode to a metered pool. The subsidies that were quietly propping up headless agent economics are gone.

Stanford research found ~70% of agent tokens are waste — re-reading files, exploring dead ends, snowballing context. A single SWE-Bench Pro task on Opus 4.7 can burn $10–$15 in tokens for one PR.

The teams that thrive in the next phase won't have the biggest budgets. They'll be the ones who treat tokens like a resource.

How it works

Persistent context, delivered just-in-time

Index your codebase once. Plug into your agent. Your agent stops paying to re-discover your architecture on every task.

1

Index once

Connect your repos. Code Lexica builds a deep, persistent model of your architecture, dependencies, and conventions.

2

Plug into your agent

One MCP config block. Works with Claude Code, Cursor, Copilot, Codex, Gemini CLI — or any MCP client.

3

Just-in-time context

Your agent asks for exactly what it needs. Scoped, structured answers — not a firehose of repo content.

Platform

More than just the MCP server

Code Lexica's persistent context model also powers reports, codebase chat, spec generation, and inline PM workflows.

Why quality also improves

Cheaper tokens are only half the story.

Persistent, structured context doesn't just save money — it makes the agent's first attempt more likely to be correct.

Evidence-backed answers

Every Code Lexica response references exact files and functions. Your agent stops inventing APIs that don't exist.

Standards before generation

Org conventions, preferred libraries, and error-handling patterns ship into the prompt — so the first draft is already idiomatic.

Higher first-pass quality

Persistent, structured context beats grep'd file dumps. Fewer retries, fewer rejected PRs, faster merge.
