About this gig
Your agent forgets everything the second the session ends. MCP shows connected, but there's zero communication with memory. Ask it something from yesterday, it has no idea. I give it real memory that works.
I set up pgvector as a proper vector database, wired through a working MCP server so Claude Code, Hermes Agent, or OpenClaw can save and recall context correctly. Second-brain style memory you can browse, not a black box.
What's included:
- pgvector vector database setup, connected to your agent
- MCP server configured, verified end-to-end, no silent failures
- HNSW indexing for fast search at scale
- Neo4j knowledge graph for relationship-based memory
- Second-brain style notes integration for browsable memory
- Full source code and clear comments, never locked out
You send access, I diagnose what's connected versus what only looks connected, build the memory layer, and verify your agent genuinely remembers it all now.
If you've built everything else and the missing piece is memory that works, this is it.
Message me what you're building, I'll tell you exactly what it needs.

I build, fix, and harden self-hosted AI agent systems: Hermes Agent, OpenClaw, Jarvis AI, n8n, Claude Code, MCP servers, on your VPS or Mac Mini, not a monthly SaaS.
What I cover:
Setup and deployment of your AI agent stack
Agent memory (pgvector, agentmemory, RAG)
Fixing broken, crash-looping systems
Hardening and monitoring long term
Most sellers handle one piece. I work the whole ecosystem, not stitching freelancers work together.
Message your setup and goal, I confirm scope first.
FAQ
My MCP server shows "connected" but my agent doesn't actually remember anything. Can you fix that?
Yes, this is exactly what I fix. It's usually a broken read/write path between the MCP handshake and the actual memory store — I trace it end-to-end and fix the real cause.
What is pgvector, and why does my agent need it?
pgvector turns a regular Postgres database into a vector database, letting your agent store and search context by meaning rather than exact keywords. Without it, your agent has no real long-term memory
Do I need Neo4j too, or is pgvector enough?
Pgvector alone covers most memory needs. Neo4j is worth adding only if your agent needs to understand relationships between pieces of information, not just retrieve similar text.
What's the "second-brain" style memory about?
It's an option to make your agent's memory browsable as readable notes, not just raw database entries, so you can see and edit what it "knows."
What access do you need from me?
Server/VPS access and details on your current agent setup (Claude Code, Hermes Agent, OpenClaw, etc).
: Is this a one-time setup or ongoing?
One-time setup. If you also want ongoing monitoring, that's covered separately in my other gig (Langfuse/OpenTelemetry).
