What is mnemo-mcp CLAUDE.md?

A set of project instructions for mnemo-mcp, a standalone MCP server that gives compatible AI agents persistent, associative memory stored locally. MCP is a standard way for AI tools to connect to services.

It helps developers install, build, run, configure, and inspect mnemo-mcp, including its embedding provider and SQLite memory database.

It documents how to build and run the server and how its memory can fade unless it is reinforced.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00834	$0.00834
Opus 5.5	$0.00334	$0.00334
Sonnet 5.5	$0.00167	$0.00167
Haiku 4.5	$0.00083	$0.00083

Security

Grade A, and why

mnemo-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CLAUDE.md — mnemo-mcp

What is mnemo-mcp

A standalone MCP server that provides persistent, decaying, associative memory to any MCP-compatible AI agent. Local-first, pluggable embeddings, zero mandatory cloud dependency.

Key differentiator

Cognitive decay. Memories fade unless reinforced. Core memories persist. This isn't a flat database — it's a portable hippocampus.

Quick Reference

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
