Codebase Memory MCP
Capped at 70: no passing tool call yet; the tests add up to 95. Why scores are capped
Test points add up to 95; the score is capped at 70 until a tool call passes. Not a quality or security rating. Methodology

Install note: npm postinstall (install.js) downloads a platform binary from the project's GitHub Releases (v0.12.1). Its SHA-256 is checked against checksums.txt from that same release, so the checksum is not an independent check.

Summary: Codebase Memory MCP completed an MCP handshake without credentials and exposed 17 tools.
Evidence summary
- Handshake
- pass
- Tools listed
- 17
- Context cost
- 4,283 model-visible tokens (name, description, inputSchema; tiktoken cl100k_base)
Extra payload (sent by the server, usually not read by the model): 457 tokens (largest: annotations ≈443); raw tools/list total 4,740. Clients differ in what they forward. ranking · add up your servers' context cost - API key

Local-model readiness
Schema context cost: ~4,283 tokens for 17 tools (19,046 bytes) · about 52% of an 8k context. Method: tiktoken cl100k_base over compact JSON of name+description+inputSchema (approximate).
Small-model friendly (schema heuristic, not a model result): low.
Small-model task runs: Not yet tested.
What we tested and what we didn't
Tested on 2026-10-24
- Install from the registry
- We connected with no credentials and asked for its tool list: it listed 17 tools (Method details: MCP
initializethentools/list) - Maintenance signals (last push, archived/deprecated status)
- Docs (README length, install and config example)
- License (OSI-approved or not)
- Tool-schema token cost (estimate)
Not tested
- Security: not audited (no code review, no permission or data-flow analysis)
- Real tasks (no functional task runs yet)
- Behaviour with real credentials or a real account
- Performance, rate limits or load
- Correctness of results beyond the listed tasks
Methodology: how we test. A high score means it installs and responds, not that it is safe to give it access to your data.
Known security issues
Checked on 2026-10-27 for version 0.12.1 against OSV, GitHub advisories, GitHub repository advisories. Scope: the package itself; dependencies not scanned.
No published advisories found in OSV and GitHub advisories for codebase-memory-mcp 0.12.1 as of 2026-10-27. This is not a security audit.
