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 | $0.00450 | $0.00450 |
| Opus 5.5 | $0.00180 | $0.00180 |
| Sonnet 5.5 | $0.00090 | $0.00090 |
| Haiku 4.5 | $0.00045 | $0.00045 |
Grade A, and why
simple-memory-mcp copilot-instructions.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.
What it actually says
Simple Memory MCP Server
TypeScript MCP server for persistent memory storage with SQLite FTS5. Works as both MCP server and CLI tool.
Quick Reference
Build & Test (All operations < 10 seconds)
npm install # Install dependencies
npm run build # Build TypeScript → JavaScript
npm test # Run all tests
CLI Commands
# Store
node dist/index.js store --content "text" --tags "tag1,tag2"
# Search
node dist/index.js search --query "text" # By content
node dist/index.js search --tags "tag1" # By tags
# Update
node dist/index.js update --hash "abc..." --content "new text" --tags "new,tags"
# Delete

node dist/index.js delete --hash "abc..." # By hash
# Stats
node dist/index.js stats
Database
- Default:
./memory.db - Custom: Set
MEMORY_DB=/path/to/dbenvironment variable - Format: SQLite with FTS5 full-text search, WAL mode

Architecture
- ES Modules: Use
.jsextensions in imports - TypeScript: Target ES2022, outputs to
dist/ - Database: better-sqlite3 with FTS5, prepared statements
- MCP: @modelcontextprotocol/sdk
- Performance: Sub-millisecond operations, 2,000-10,000 ops/sec
Troubleshooting
- Module errors: Run
npm install - Build errors: Run
npm run build - Database errors: Check
MEMORY_DBpath is writable
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.
