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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00016 | $0.00661 |
| Opus 5.5 | $0.00006 | $0.00264 |
| Sonnet 5.5 | $0.00003 | $0.00132 |
| Haiku 4.5 | $0.00002 | $0.00066 |
Grade A, and why
gitnexus-exploring 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.

Exploring Codebases with GitNexus
When to Use
- "How does authentication work?"
- "What's the project structure?"
- "Show me the main components"
- "Where is the database logic?"
- Understanding code you haven't seen before
Workflow
1. READ gitnexus://repos → Discover indexed repos
2. READ gitnexus://repo/{name}/context → Codebase overview, check staleness
3. gitnexus_query({query: "<what you want to understand>"}) → Find related execution flows
4. gitnexus_context({name: "<symbol>"}) → Deep dive on specific symbol
5. READ gitnexus://repo/{name}/process/{name} → Trace full execution flow
If step 2 says "Index is stale" → run
npx gitnexus analyzein terminal.
Checklist
- [ ] READ gitnexus://repo/{name}/context
- [ ] gitnexus_query for the concept you want to understand
- [ ] Review returned processes (execution flows)
- [ ] gitnexus_context on key symbols for callers/callees
- [ ] READ process resource for full execution traces
- [ ] Read source files for implementation details
Resources
| Resource | What you get |
|---|---|
gitnexus://repo/{name}/context |
Stats, staleness warning (~150 tokens) |
gitnexus://repo/{name}/clusters |
All functional areas with cohesion scores (~300 tokens) |
gitnexus://repo/{name}/cluster/{name} |
Area members with file paths (~500 tokens) |
gitnexus://repo/{name}/process/{name} |
Step-by-step execution trace (~200 tokens) |
Tools
gitnexus_query — find execution flows related to a concept:
gitnexus_query({query: "payment processing"})
→ Processes: CheckoutFlow, RefundFlow, WebhookHandler
→ Symbols grouped by flow with file locations
gitnexus_context — 360-degree view of a symbol:
gitnexus_context({name: "validateUser"})
→ Incoming calls: loginHandler, apiMiddleware
→ Outgoing calls: checkToken, getUserById
→ Processes: LoginFlow (step 2/5), TokenRefresh (step 1/3)
Example: "How does payment processing work?"
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.

gitnexus-exploring is a skill published in the GitHub repository doobidoo/mcp-memory-service (2,089 stars, last pushed yesterday), licensed Apache-2.0. It adds 16 tokens to every session and 661 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
