BuyAPI is an MCP server with 7 tools an agent can call, among them stacks.findSimilar, stacks.recommend, vendors.compare. It answers at https://buyapi.ai/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 20 October 2026, succeeded.
Vendor intelligence for AI coding agents choosing developer tools and stacks.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
stacks.findSimilar | Finds reviewed public stack examples related to a vendor, or recent curated stack examples. Use this when the user asks who uses a tool, what similar builders use, or wants examples of real stack combinations. Do not use it as a generic rec Inputs: vendorId, limit |
stacks.recommend | Recommends a complete stack from BuyAPI's corpus with a structured decision matrix, cost estimate, assumptions, unknowns, alternatives, and sources. Use this when the user is starting a project or asks for a complete multi-layer stack choic Inputs: projectDescription, constraints, workload, stackContext, stackFacts |
vendors.compare | Compares two or more already-known BuyAPI vendors for a specific workload or decision. Use this when the candidate set is known, for head-to-head questions like "Convex vs Supabase vs Neon for a realtime SaaS" or "Stripe vs Paddle for a mar Inputs: vendorIds, query, workload |
vendors.details | Follow-up tool for one known vendor. Retrieves detailed pricing, features, limits, gotchas, comparisons, and source provenance. Call vendors.resolve first unless the user already provided a BuyAPI vendor ID like /database/supabase. Use this Inputs: vendorId, query |
vendors.estimateCost | Produces directional monthly cost estimates from BuyAPI pricing data and explicit workload inputs. Use this only when the user asks for cost math and provides explicit workload inputs. Missing workload fields are returned as assumptions or Inputs: vendorIds, category, workload |
vendors.evidence | Returns recent reviewed BuyAPI evidence rows for a vendor, category, stack, or comparison. Use this when the user asks why BuyAPI believes something, what sources support a recommendation, or what recent human/source/opinion/history signals Inputs: subjectType, subjectId, limit |
vendors.resolve | First stop for category-specific vendor recommendations and vendor ID discovery. Finds BuyAPI vendor IDs for a user question; provide category when known. Use this when the user asks which provider in a category fits their constraints. With Inputs: query, category |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://buyapi.ai/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.thesnakefang. Endpoint host: buyapi.ai. ARD identifier: urn:air:io.github.thesnakefang:mcp:buyapi-mcp.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
