# Avalon Memory Crystal Server (amcs)
|
|
|
|
|
|
|
|
A Go MCP server for capturing and retrieving thoughts, memory, and project context. Exposes tools over Streamable HTTP, backed by Postgres with pgvector for semantic search.
|
|
|
|
## What it does
|
|
|
|
- **Capture** thoughts with automatic embedding and metadata extraction
|
|
- **Search** thoughts semantically via vector similarity
|
|
- **Organise** thoughts into projects and retrieve full project context
|
|
- **Summarise** and recall memory across topics and time windows
|
|
- **Link** related thoughts and traverse relationships
|
|
|
|
## Stack
|
|
|
|
- Go — MCP server over Streamable HTTP
|
|
- Postgres + pgvector — storage and vector search
|
|
- LiteLLM — primary AI provider (embeddings + metadata extraction)
|
|
- OpenRouter — default upstream behind LiteLLM
|
|
|
|

Config is YAML-driven. Copy `configs/config.example.yaml` and set:
|
|
|
|
- `database.url` — Postgres connection string
|
|
- `auth.keys` — API keys for MCP endpoint access
|
|
- `ai.litellm.base_url` and `ai.litellm.api_key` — LiteLLM proxy
