Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/alphaplapplap/mcp-memory-service/agents-mdgit clone --depth 1 https://github.com/alphaplapplap/mcp-memory-serviceWhat 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 | $0.01385 | $0.01385 |
| Opus 5 | $0.00692 | $0.00692 |
| Sonnet 5 | $0.00277 | $0.00277 |
| Haiku 4.5 | $0.00138 | $0.00138 |
Grade A, and why
mcp-memory-service AGENTS.md scanned grade A with 1 finding 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

AI coding agent instructions for MCP Memory Service - a universal memory service providing semantic search and persistent storage for AI assistants.
Project Overview
MCP Memory Service implements the Model Context Protocol (MCP) to provide semantic memory capabilities for AI assistants. It supports multiple storage backends (SQLite-vec, ChromaDB, Cloudflare) and works with 13+ AI applications including Claude Desktop, VS Code, Cursor, and Continue.
Setup Commands
# Install dependencies (platform-aware)
python install.py
# Alternative: UV installation (faster)
uv sync
# Start development server
uv run memory server
# Run with inspector for debugging
npx @modelcontextprotocol/inspector uv run memory server
# Start HTTP API server (dashboard at https://localhost:8443)
uv run memory server --http --port 8443
Testing
# Run all tests
pytest tests/
# Run specific test categories
pytest tests/test_server.py # Server tests
pytest tests/test_storage.py # Storage backend tests
pytest tests/test_embeddings.py # Embedding tests
# Run with coverage
pytest --cov=mcp_memory_service tests/
# Verify environment setup
python scripts/validation/verify_environment.py
# Check database health
python scripts/database/db_health_check.py
Code Style
- Python 3.10+ with type hints everywhere
- Async/await for all I/O operations
- Black formatter with 88-char line length
- Import order: stdlib, third-party, local (use
isort) - Docstrings: Google style for all public functions
- Error handling: Always catch specific exceptions
- Logging: Use structured logging with appropriate levels

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.

mcp-memory-service AGENTS.md is an instructions file published in the GitHub repository alphaplapplap/mcp-memory-service (9 stars, last pushed 11mo ago), licensed Apache-2.0. It adds 1,385 tokens to every session, about $0.0069 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
