FrontMCP

FrontMCP provides a TypeScript framework for building MCP (Model Context Protocol) servers. It enables developers to create tools, define typed schemas, and integrate authentication, background jobs, and deployment options across Node.js, Vercel, AWS Lambda, Cloudflare Workers, and browsers. The open‑source project is Apache 2.0 licensed and offers extensive documentation, examples, and a playground for rapid prototyping of AI‑driven applications.

FrontMCP is listed with 4 APIs on the APIs.io network, including Authentication overview API, core API, SDK overview API, and 1 more. Tagged areas include Artificial Intelligence, TypeScript, Framework, Open Source, and MCP.

The FrontMCP catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

FrontMCP’s developer surface includes sandbox, changelog, documentation, getting-started guide, engineering blog, and 15 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship Ask about this →
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author Ask about this →
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented) Ask about this →
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0 Ask about this →
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented) Ask about this →
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document Ask about this →

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/frontmcp-dev/apis.yml: open an issue on github.com/api-evangelist/frontmcp-dev to ask a question or point us at an artifact you publish.
