buyapi
Unbiased vendor intelligence MCP server that helps AI agents and developers make informed infrastructure decisions by providing current, structured, neutral vendor comparisons and recommendations.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
vendors.resolveFinds BuyAPI vendor IDs for a user question. Category is optional; provide it when known. Use this for vendor discovery before vendors.details, or when the user asks which provider in a category fits their constraints. Do not use this for local coding/debugging/docs questions unless they involve ch…
vendors.detailsRetrieves detailed vendor information including pricing, features, limits, gotchas, comparisons, and source provenance. Call vendors.resolve first unless the user already provided a BuyAPI vendor ID like /database/supabase.
vendors.evidenceReturns recent BuyAPI evidence rows for a vendor, category, stack, or comparison. Use this when the user asks why BuyAPI believes something, what sources support a vendor page, or what recent human/source signals exist.
stacks.findSimilarFinds public stack profiles 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.
vendors.compareCompares two or more BuyAPI vendors for a specific workload or decision. Use this for head-to-head questions like "Convex vs Supabase vs Neon for a realtime SaaS" or "Stripe vs Paddle for a marketplace".
vendors.estimateCostProduces deterministic monthly cost estimates from BuyAPI pricing data and explicit workload inputs. Use this when the user asks for cost math. Missing workload fields are returned as assumptions or unknowns instead of being hallucinated.
stacks.recommendRecommends 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 stack choice. Do not use this for local coding/debugging/docs questions that do no…
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
BUYAPI_API_KEYThe local package reads either or the key stored by buyapi login:BUYAPI_API_URLTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
7/7 tools missing one or more hints — vendors.resolve (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); vendors.details (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); vendors.evidence (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +4 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Shell command execution
2 child_process/subprocess calls in production code — runs shell commands (src/index.ts:895, src/lib/login.ts:77)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets not logged
11 secret values sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.1 (high), @modelcontextprotocol/sdk@1.12.1 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
