foundry-mcp-com

Foundry MCP provides a bridge between the Foundry Virtual Tabletop (VTT) platform and large language model (LLM) assistants such as Claude, ChatGPT, Codex, and Cursor. It enables AI-driven gameplay by allowing bots to roll dice, manage combat, write journal entries, move tokens, import compendium data, and interact with game mechanics without running a local server. The service offers a public REST API for bots and custom tools, free to start, and integrates with the MCP client ecosystem. It supports D&D 5e, PF2e and other systems, offering features like initiative tracking, skill checks, spell casting, and world time management, all via outgoing connections only.

foundry-mcp-com publishes 5 API contracts indexed on the APIs.io network, including Public API, Tier Adventurer API, Tier Dm API, and 2 more. Tagged areas include FoundryVTT, MCP, AI, Gaming, and Automation.

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

foundry-mcp-com’s developer surface includes documentation, authentication, API reference, and 14 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
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)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too

4 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Access Clarity scores 21.1 — up to +15.8 composite points
Operational Transparency scores 0.0 — up to +13.0 composite points
Developer Ergonomics scores 35.0 — up to +13.0 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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/foundry-mcp-com/apis.yml: open an issue on github.com/api-evangelist/foundry-mcp-com to ask a question or point us at an artifact you publish.
