MCP Integration: Live Tool Recommendations for Agent Decision-Making

Agents built on google/adk-python regularly need to recommend or pick a SaaS tool for a task — today they either hardcode the choice or pull from outdated training data, which produces systematically wrong picks.

Vest is a drop-in MCP server that turns "which tool for X" into a structured query — returns live ranked recommendations from an offer graph that tracks real-world pricing, availability, popularity, and deployment paths. No hallucination, no stale data.

Integration shape is minimal: a single MCP tool node (Vest.recommendTool, Vest.compareTools, Vest.checkOffer) that google agents call exactly like any other tool. Zero changes to the framework's existing tool surface.

The upside for builders: agents stop hallucinating tool picks; users get accurate, verifiable recommendations; the framework looks more capable without any data work on your end. We handle the offer graph and real-time verification.

(Optional secondary value: for vendors and tool operators in the graph there's a verified-deployment + settlement layer, so when an agent actually picks something the transaction is tracked end-to-end.)

Happy to open a PR with a reference integration. Docs are at getvest.ai/mcp — would love to chat about how this fits into google's tool-calling roadmap.

Hi maintainers, I’m interested in helping with this, but I’d like to confirm the preferred direction before opening a PR.

Since ADK already supports generic MCP integration through McpToolset and Streamable HTTP/SSE/stdio connection params, would you prefer one of these approaches?

1. Add a Vest-specific MCP sample under contributing/samples/mcp/
2. Add a more generic “remote MCP recommendation server” sample/docs note that could apply to Vest and other MCP servers
3. Wait until there is a concrete, stable MCP endpoint/tool schema before making any repo changes

Also, the linked docs at https://getvest.ai/mcp currently return 404 for me, so an executable sample would need a stable endpoint and expected tool names/schemas.

Happy to send a small focused PR once the preferred direction is clear.
