No copy-paste install info for "Open Brain MCP" yet — see the docs or source repo.
Save this thought to Open Brain MCP and check whether it duplicates existing entries: 'Build a weekly report assistant for team knowledge capture.' Then run a semantic search for similar past notes.
Returns the save result, possible duplicates, and a list of semantically similar previous notes.
Store the following research note in Open Brain MCP and search for existing content related to 'local vector retrieval': 'We plan to build a local knowledge base with PostgreSQL and pgvector.'
Outputs the new note result and existing entries related to local vector retrieval.
Add this everyday thought to Open Brain MCP: 'Consolidate scattered meeting conclusions into a personal knowledge base.' If similar content already exists, flag it and show the most relevant entries.
Provides the write result, duplicate warning, and related entries to support ongoing personal knowledge capture.
Researchers, creators, or developers can continuously store scattered thoughts in this self-hosted second brain. Deduplication and semantic search make later review and reuse easier.
Users who need control and privacy can run this MCP server on their own hardware. It uses local embeddings and PostgreSQL with pgvector to power retrieval.
When users frequently capture notes or ideas, this tool helps identify duplicate content. That reduces redundancy and keeps the second brain easier to maintain and search.
It is a self-hosted second-brain MCP server for capturing thoughts, with deduplication and semantic search. The description says it uses local embeddings and PostgreSQL with pgvector.
Known prerequisites include your own hardware, PostgreSQL, and pgvector. The description also says it uses local embeddings; for exact installation steps, see the source repository.
The clearest difference in the provided information is that it is self-hosted, with everything running on your own hardware. For deeper comparisons, see the source repository.
