Your agents are working from noise.
Myco gives them truth.

Most memory tools store unverified summaries, duplicates, and LLM guesses. Myco builds a deterministic knowledge graph — every fact traced to its source, every query auditable, every agent working from the same truth.

One command to run the MCP server. Works with Claude, Cursor, and any MCP-compatible agent.

Run the MCP server
npx @mycobrain/mcp-server

Requires Node 18+ and a Postgres + pgvector instance. Set DATABASE_URL in your environment.

This is what it feels like when your AI actually knows you.

These are not hypothetical. These are the questions Myco answers — instantly, with sources — that no AI tool can answer today.

Client account management
What did we promise Acme Corp in the Q3 review?

Found 3 commitments across 2 emails and 1 proposal — all linked to source documents with timestamps.

Agency operations
Who are our 5 most complex active clients?

Ranked by project history, open tickets, and commitment density. Full reasoning included.

Engineering knowledge
Has anyone on the team solved this type of integration before?

Yes — the Martinez project in 2024. Here is the relevant code context and what was learned.

AI agent onboarding
Brief the new agent on the Johnson account.

Complete context pack in one API call. No manual prep. 3 years of history, structured.

Each answer is traced back to its source document. No hallucinations. No guesses.

“97% of my agent's memories were junk.”

This is not a rounding error. It is the state of memory systems today. The failure is silent until production is already paying the price.

97% JUNK RATE
Your agent's memory is worse than useless
Teams are finding memory stores packed with duplicates, hallucinations, and malformed entries. Bad memory retrieval compounds into bad decisions and wasted tokens.
SILENT FAILURES
You don't know memory is broken until later
Writes appear successful while persistence quietly fails. Teams only discover it after lost sessions, stale state, and repeated debugging loops.
STITCHED TOGETHER
Three libraries and too many failure boundaries
Checkpoint tooling, vector memory, and custom session logic drift apart over time. The result is a brittle stack that keeps breaking as your product scales.

Built for teams that are serious about AI.

Whether you are using one AI tool or running a full autonomous agent stack, Myco is the memory layer you have been missing.

AI-forward marketing & growth agencies
The pain
Managing context across dozens of clients. Agents start from scratch every session. Hours lost assembling briefings.
The value
Every agent you deploy already knows every client. Commitments, history, preferences — one query away.
New agent onboards to a client account in seconds, not hours.

Companies building with AI
The pain
AI features that don't know your customers. Product intelligence that doesn't improve. Token costs that grow faster than value.
The value
Customer-facing AI that knows purchase history, support history, preferences, and account context — without stuffing it into every prompt.
60-80% reduction in tokens per AI call. Better answers. Lower costs.

CTOs building agentic stacks
The pain
Agents that contradict each other. No shared source of truth. No audit trail. No governance layer. Bespoke RAG pipelines that break and drift.
The value
One MCP endpoint replacing every custom retrieval system. Deterministic facts with full provenance. Human review queue built in.
Enterprise-grade memory infrastructure — without building it yourself.

We hit this wall at our own agency. Then we built the fix.

Good Guys LA has been running autonomous AI agent workflows since early 2025. We had Claude, Cursor, and Paperclip agents running across a dozen client accounts. Every agent started from scratch. Agents contradicted each other. We spent an hour every morning assembling context for work that should have been instant.

We built Myco because we needed it. Today, every agent we run — across every client — queries a single, growing, auditable memory. We don't brief agents anymore. We don't repeat context. We don't correct contradictions. Our AI stack gets smarter every week.

We built Myco because we needed it. Now we are opening it to teams who want the same.

From scattered files to structured intelligence in three steps.

No complex setup. No custom pipelines. Myco handles the hard parts so your AI can focus on the work.

01
Connect your sources
Link Gmail, Google Drive, Slack, Notion, GitHub, or drop files directly. Myco handles every format: PDFs, emails, spreadsheets, transcripts, images. Your data stays on your infrastructure.
02
Myco extracts and structures
A deterministic core computes facts — file hashes, entities, relationships, timelines. No LLM guesses at the foundation. Everything is traced to its source with a full audit trail. Medium-confidence items go to a human review queue.
03
Your agents get memory
Every AI tool in your stack — Claude, ChatGPT, Cursor, or your own agents — calls one MCP endpoint and gets structured, auditable context. No custom integrations. No context stuffing. Just memory.

Built different. Not just another search box.

Most “AI memory” tools index documents and call it memory. Myco builds a living, growing, auditable knowledge graph your agents can actually reason over.

Foundation
Deterministic core — facts, not guesses
The foundation of Myco is a program, not a prompt. File metadata, entity extraction, and relationship mapping are computed deterministically. LLMs are boxed into an advisory role for synthesis only, and medium-confidence outputs are routed for review.

MCP
One endpoint for every AI tool
Claude, ChatGPT, Cursor — every agent queries the same memory. No custom integrations. No duplicate retrieval.

Provenance on every accepted claim
Ask Myco why it believes something and it shows the source chain for accepted claims: original document, extraction model, confidence score, timestamp.
Intelligence that compounds daily
Every new file, agent action, and conversation enriches the knowledge graph. Myco gets smarter over time — in your favor.
Multi-agent shared memory
Every agent in your stack — Claude, Cursor, Paperclip — reads from the same source of truth. No contradictions. No repeated context.

With self-hosted Myco, your data never has to leave your infrastructure.

Every time your team pastes a client contract into ChatGPT, that document travels to OpenAI’s servers. Every document you feed an AI agent as context crosses someone else’s infrastructure. Most teams have not fully considered what this means.

Raw documents stay yours
Myco processes documents on your infrastructure. Agents receive structured facts — not raw documents — as context. Your contracts, client files, and IP never need to travel to external servers.
Structured facts, not raw data
When an agent queries Myco, it gets precise, structured context — not a dump of the original document. This dramatically reduces the amount of sensitive data in any single AI call.
Full audit trail
Every piece of knowledge has a source. Every query is logged. Every agent access is recorded. You know exactly what your AI read, when, and why — which answer came from which document.
Self-hosted for complete control
For teams with strict data residency requirements — legal, finance, healthcare — Myco offers a full self-hosted deployment. Your infrastructure. Your data. Your rules.

We looked at every alternative. Here is the honest comparison.

We researched MemPalace, Mem0, Glean, LangChain, Notion AI, and more before building Myco. None of them solved the problem. Here is why.

vs. Glean / Notion AISearch tools built for humans browsing documents. Myco gives agents structured facts they can reason over. Built for the agent era, not the search era.
vs. Mem.ai / Mem0Built for personal memory, not a shared company memory contract. Myco gives teams deterministic facts, source-trace audit trails, and one structured memory layer for every agent.
vs. RAG / LangChainRequires you to build and maintain retrieval pipelines, embedding stores, and chunking logic. Myco delivers the same capabilities as a managed service with deterministic guarantees and a built-in review queue.

The compounding advantage.

AI tools give you a powerful day-one capability. Myco gives you something better: an advantage that grows every single day.

Without Myco
  • Every AI session starts from zero
  • 30%+ of AI budget goes to re-establishing known context
  • Agents contradict each other with no resolution
  • Knowledge walks out the door when people leave
  • Raw client documents flowing through external servers
  • AI stack is exactly as smart as day one
With Myco
  • Every agent starts informed — client history, commitments, context
  • 60–80% reduction in tokens per agent call
  • Single source of truth — agents coordinate, not contradict
  • Institutional knowledge grows and persists permanently
  • Raw data processed on your infrastructure only
  • AI stack gets smarter every single day

The teams that build persistent memory into their AI stack today will have a compounding intelligence advantage that is very hard to catch up to in 2-3 years. The teams that don’t will still be pasting context into chat windows.
