copilot-memory-store
Provides a local JSON-backed memory store for context engineering with GitHub Copilot and MCP clients. Includes a CLI REPL to add/search/compress/delete/purge/export memories, and an MCP stdio server exposing tools and resources to let Copilot agents read/write/search memories and inject shaped/compressed context for tasks (optionally using DeepSeek for summarization/context shaping).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Local JSON storage with no documented auth/authorization boundaries increases risk if exposed to untrusted processes/users. DeepSeek API key is referenced via .env; README does not describe logging/redaction behavior. No TLS/RPC encryption is described because MCP is stdio (transport-local), so confidentiality depends on local host environment. Error handling, input validation boundaries, and path/file safety are not detailed in the provided README.
⚡ Reliability
Best When
You want a lightweight, local-first MCP/CLI memory workflow for Copilot-style agents, and you can accept JSON-file storage and stdio MCP transport.
Avoid When
You need robust security controls for untrusted remote users or you require enterprise-grade compliance features and hardened multi-tenant access control.
Use Cases
- • Persisting developer preferences and architectural decisions as searchable memories
- • Retrieval-augmented context injection for Copilot tasks
- • Budget-constrained memory compression (deterministic and optional LLM-assisted)
- • Building or testing MCP-based agent workflows with tools like memory_write/search/compress/delete/export
- • Team knowledge capture: store decisions/tags/recency and recall them during refactors or implementations
Not For
- • Multi-user production deployments that require strong authentication/authorization boundaries
- • Use cases needing server-side storage, backups, or managed persistence
- • Environments where writing to a local file is unacceptable (e.g., strict sandboxing without filesystem access)
- • Applications requiring documented REST/HTTP API semantics, pagination, and rate limiting
Interface
Authentication
No explicit auth mechanism is documented for the MCP server/CLI. Configuration centers on local filesystem path (MEMORY_PATH) and optional DeepSeek credentials for LLM-assisted features.
Pricing
Open-source MIT package; local execution implies no direct service pricing, but optional DeepSeek calls may incur third-party API charges.
Agent Metadata
Known Gotchas
- ⚠ MCP prompts are not supported by VS Code GitHub Copilot (per README); prompts should be tested via MCP Inspector or other MCP clients.
- ⚠ The MCP server runs over stdio; agents must be launched with the correct command/args/build output (dist/mcp-server.js) and MEMORY_PATH environment.
- ⚠ Demo prefilled data may exist in project-memory.json; README advises deleting/overriding MEMORY_PATH before real use.
