by occasionallysomebody • Uncategorized
A zero-dependency MCP server providing Claude with a persistent personal knowledge base.
Example Use Cases
- 1
Store and retrieve personal notes persistently.
- 2
Perform full-text and tag-based searches on knowledge data.
- 3
A zero-dependency, local knowledge base server compatible with MCP.
Description
This MCP server implements the Model Context Protocol to enable Claude AI to interact with a personal knowledge base stored locally. It supports adding, searching, listing, deleting notes, and retrieving statistics, all persisted in a JSON file without external dependencies. The server communicates over JSON-RPC 2.0 via stdin/stdout, making it lightweight and easy to integrate with Claude Desktop or Claude Code CLI.

store_knowledge
Store a new piece of knowledge in the shared knowledge base. Knowledge can be conventions, decisions, patterns, pitfalls, facts, debug notes, or process documentation. Optionally link this entry to existing entries.

query_knowledge
Search the shared knowledge base using free-text queries. Results are ranked by relevance. Accessing knowledge automatically records the access for analytics. Use this to find conventions, decisions, patterns, pitfalls, and other team knowledge. Content is truncated in results — use `get_knowledge` to read full entries. Entries marked needs_revalidation=true may be stale due to changes in linked entries — verify their accuracy before relying on them, then use `reinforce_knowledge` if still correct or `update_knowledge` to fix outdated content.

get_knowledge
Retrieve the full content of a knowledge entry by ID. Supports short ID prefixes (minimum 4 characters) — if the prefix uniquely identifies an entry, it will be resolved automatically. Use this after query_knowledge or list_knowledge to read the complete content of an entry (search results return truncated content). Accessing an entry automatically reinforces it. If the entry has needs_revalidation=true, it may be stale due to changes in linked entries — verify its accuracy before relying on it, then use `reinforce_knowledge` if still correct or `update_knowledge` to fix outdated content.

list_knowledge
Browse and filter knowledge entries without a text search query. Use this to see what knowledge exists by type, project, scope, or status. Unlike query_knowledge, this does NOT auto-reinforce entries. Entries marked needs_revalidation=true may be stale due to changes in linked entries — verify their accuracy before relying on them, then use `reinforce_knowledge` if still correct or `update_knowledge` to fix outdated content.

reinforce_knowledge
Explicitly reinforce a knowledge entry, confirming it is still accurate and useful. This resets the entry's inaccuracy score to 0, clearing any revalidation need. Also records an access to keep the entry's last_accessed_at current.
