mcp-memory-service is a self-hosted memory backend that lets AI agents store and retrieve shared project context through REST, MCP, OAuth, a command-line interface, and a dashboard. It is intended for agent pipelines and clients such as LangGraph, CrewAI, AutoGen, Claude Desktop, and OpenCode, with support for knowledge graphs and memory consolidation. The catalogue includes skills, agents, commands, instructions, hooks, a setting, an MCP entry, and a plugin for its workflows.

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 | $0.00752 | $0.00752 |
| Opus 5.5 | $0.00301 | $0.00301 |
| Sonnet 5.5 | $0.00150 | $0.00150 |
| Haiku 4.5 | $0.00075 | $0.00075 |
Grade A, and why
mcp-memory-service AGENTS.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 4d 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.
How it starts
The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Issue claim automation
Issues with both good first issue and auto-assign accept a standalone
/claim comment. Wait for the actual assignment and confirmation before working;
the confirmation approves only the issue's prepared scope. Other issues retain
manual maintainer confirmation. See CONTRIBUTING.md for the full rules.
GitNexus MCP
This project is indexed by GitNexus as mcp-memory-service (6259 symbols, 18031 relationships, 300 execution flows).
GitNexus provides a knowledge graph over this codebase — call chains, blast radius, execution flows, and semantic search.
Always Start Here
For any task involving code understanding, debugging, impact analysis, or refactoring, you must:
- Read
gitnexus://repo/{name}/context— codebase overview + check index freshness - Match your task to a skill below and read that skill file
- Follow the skill's workflow and checklist
If step 1 warns the index is stale, run
npx gitnexus analyzein the terminal first.

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.
