The intelligence
your MCP agents
are missing.

Every tool call is a blind guess — the LLM reads descriptions and picks. Physarum is the shared intelligence network that learns from every call, routes to the optimal server, and compounds with every agent that joins.

What the network
learns for you

All from telemetry your agents already produce. Zero instrumentation beyond pointing to the proxy.

Failure Prediction
Jira MCP degrades Tuesdays at 18:00 UTC. The 10,001st agent doesn't learn the hard way.

Cost Optimization
3 tokens vs 800 for the same result. Identifies the cheapest path that meets your quality floor.

Model Pairing
Sonnet + GitHub MCP = 94% success. Not all models work equally well with all servers.

Brave Search works best with under 6-word queries. Patterns that improve success automatically.

Rescue Chains
When Jira fails, try Linear then ClickUp. Recovery sequences built from observed patterns.
Setup

One change.
Full intelligence.

Replace every MCP server URL with a single proxy endpoint. Routing, learning, and fallback handled automatically.

✓Self-host on any machine or cloud — zero vendor lock-in
✓Shared intelligence is opt-in, anonymised, and aggregated
✓Apache 2.0 — fully open, no proprietary hooks
✓Cold-start bootstrapped with industry benchmarks

Every agent
makes it smarter.

The network compounds. The more agents route through Physarum, the more precise the intelligence becomes — for everyone.
