In-Memoria
In Memoria is an on-machine (local-first) MCP server that learns from a codebase and exposes persistent “project blueprint” context, semantic/pattern search, file routing, and work-memory/pattern recommendations to AI coding assistants.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Local-first design reduces exposure over the network, but there is no documented authentication/authorization for MCP tool usage and no documented transport security needs because it’s invoked locally. Embeddings and learned data are stored locally (SQLite + SurrealDB with SurrealKV) but no details are provided about encryption at rest, access controls, or data deletion. Dependency list includes standard libraries; no vulnerability status is provided in the README/manifest. Agents should assume tool calls can access local codebase content and learned artifacts, so host/permissions hardening is important.
⚡ Reliability
Best When
You want local-first, persistent coding assistance where an MCP-capable agent repeatedly queries learned context, search, and routing for the same repository over time.
Avoid When
You need a server with strong enterprise-grade access controls, documented rate limits, and guaranteed consistency/SLA; In Memoria is explicitly described as early-stage/WIP.
Use Cases
- • Persistent AI-assisted codebase navigation across sessions
- • Generating compact project context (tech stack, entry points, architecture) for an agent
- • Semantic/pattern-based code search to find relevant code by intent
- • Routed feature implementation suggestions (e.g., “password reset” → likely files)
- • Capturing and reusing architectural decisions and coding conventions (work memory/pattern prediction)
Not For
- • Multi-tenant hosted deployments without considering data isolation
- • Cases requiring a hosted HTTP API with standard auth and rate limits
- • Security-sensitive environments without auditing local storage and data handling
- • Use as a general knowledge base unrelated to a specific local codebase
Interface
Authentication
The README and manifest describe local-first MCP server usage via CLI. No authentication mechanism, API keys, or scope model is described for MCP tool calls.
Pricing
Open-source (MIT) based on repository metadata; pricing not applicable beyond local environment costs.
Agent Metadata
Known Gotchas
- ⚠ MCP tools are ignored unless the chat is in the agent/appropriate mode (not Ask/Edit)
- ⚠ MCP server must be running/configured (e.g., Claude Desktop/MCP config or VS Code .vscode/mcp.json)
- ⚠ Large codebases can be slow on first analysis; agents may time out or appear unresponsive during learning/ingestion
- ⚠ “Status: Work in Progress” and README notes documentation may be incomplete; tool behavior/edge cases may change
