Agent Search MCP
Search infrastructure that agents can inspect and control
Problem
Agent workflows search repeatedly, so a single API creates a trade-off between cost, coverage, and verifiability.
Product judgement
The decision was not to find a cheaper search API, but to treat search as a product capability with multi-source verification, progressive disclosure, and replaceable engines.
Prototype and system
An engine registry, tool-level engine selection, and fused ranking made self-hosted multi-engine retrieval available through MCP.
Current evidence
An external-PR investigation that scanned 93 open-source agent projects selected it as an architecture-validation case in the MCP search category.
Next step
Turn search quality, cost, and maintenance signals into reproducible evaluation instead of merely adding more engines.
