Is the Codebase Memory MCP skill free?

Yes. The skill itself is free from GitHub · DeusData. SkillProof publishes the install command and an independent test verdict at no cost.

How do I install Codebase Memory MCP?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Codebase Memory MCP with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Didn't pass
Tested: Jul 11, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 16, 2026

⚠ This skill is no longer available upstream. Our re-check on Jul 19, 2026 couldn't find it any more (SKILL.md not found in repo tree). The test below is what we measured on Jul 11, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

Installs cleanly and the CLI genuinely works: one-command indexing, and call-chain tracing plus definition lookup in plain TypeScript are fast and precise. But on our 8-task structural benchmark its graph missed .astro frontmatter calls, dynamic import() and type-only imports, mislabeled private functions as exported, and the stock dead-code query returned mostly false positives — the agent fell back to the tool's own text search on half the tasks to stay correct. At equal accuracy (8/8 both arms) it used 127% MORE tokens than a plain file-reading agent, not the advertised '99% fewer'.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 4/5
Triggers reliably 4/5
Output vs. baseline 3/10
Docs & honesty 2/5

What Codebase Memory MCP does

Single-binary MCP server (30k+ GitHub stars) that indexes your repo into a persistent knowledge graph: who-calls, impact analysis, dead code, Cypher queries across 158 languages. We A/B-benchmarked it against a plain file-reading agent on 8 pre-registered structural tasks: correctness parity, but only via fallbacks to its own text search — and 2.27× the tokens. Genuinely good at call-chain tracing on pure TS/JS; don't trust the graph as sole source of truth on mixed-framework codebases.

How to install Codebase Memory MCP

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.

Commands — how to trigger Codebase Memory MCP

/codebase-memory-mcp Viral code-intelligence MCP: real graph, fast queries — token claim measured inverted.

It also activates on plain-language prompts like these:

Find every caller of getSession across the repo, including .astro files
What breaks if I delete src/lib/store.ts? Include dynamic imports
List dead exports in src/lib — verify each one before claiming it's dead
