MDMA

@mobile-reality/mdma-mcp

MCP (Model Context Protocol) server for MDMA. Exposes the MDMA spec, authoring prompts, package metadata, and live GitHub documentation to AI assistants.

Tools

Tool	Purpose
get-spec	Returns the full MDMA specification (component types, JSON schemas, binding syntax, external data sources with { source, params } refs and the rows / series / options kinds, authoring rules).
get-prompt	Returns a named MDMA prompt (mdma-author, mdma-reviewer, mdma-fixer). For mdma-author, accepts an optional variantId (e.g. anthropic/sonnet-5.5, openai/gpt-6-sol) to return the model-optimised variant — use list-prompt-variants to see all available ids.
list-prompt-variants	Returns all available MDMA_AUTHOR prompt variants (id, label, description) without the prompt content. Use the id with get-prompt to fetch the model-optimised prompt.
build-system-prompt	Generates a custom MDMA prompt from structured input (domain, components, fields, steps, business rules). Pass dataSources (an external data-source catalog of rows / series / options entries) to get the full system prompt with the catalog and the rule to reference data via { source, params }.
validate-prompt	Validates a custom prompt against MDMA conventions.
list-packages	Returns all MDMA npm packages with purpose, install command, usage example, and category.
list-docs	Returns the catalog of MDMA documentation files available for fetching from the public GitHub repo.
get-doc	Fetches the latest version of a doc from raw.githubusercontent.com/MobileReality/mdma. Supports an optional ref (branch, tag, or SHA).

Distribution venues

Places where MDMA's MCP server is published or should be published. Each venue has its own submission / update flow — when releasing a new version, check each one.

Venue	Identifier / URL	Notes
npm	@mobile-reality/mdma-mcp	Publish via pnpm publish --access public --no-git-checks.
Official MCP Registry	io.github.MobileReality/mdma	Published via mcp-publisher. Namespace is case-sensitive — must match GitHub's canonical capitalization.
Glama	MobileReality/mdma	Quality + Security scores auto-evaluated periodically. Docker build config lives in the Glama admin page — re-deploy + re-release when bumping.
awesome-mcp-servers	punkpeye/awesome-mcp-servers	Entry sits under Developer Tools alphabetically.
Smithery Skills	mobilereality/mdma	Skills surface — not the MCP surface (Smithery's MCP flow is HTTP-only, unusable for stdio).
MCP.so	mcp.so/server/mdma	Submitted by Mateusz Sadowski (shown as "Submitted by" on the public page), so Title / Description / Tags / Content are edited from that account. Without access, ask Mateusz Sadowski to edit it, or use the "Claim" button next to the server name (sign in first; the verification MCP.so requires is not documented here). The page lists the tools and the npx @mobile-reality/mdma-mcp command but no version, so a new release needs no change there unless the tool set or description changes.
MCPB Desktop Extensions	Anthropic intake form	Partner queue at Anthropic. Bundle built locally; not shipped in this repo.

Release checklist — when bumping the version

Use this checklist every time you publish a new version (0.2.4 → 0.2.5, etc.).

1. Bump + test

• Update version in package.json.
• Update version string in src/index.ts (the McpServer({ version: ... }) call).
• Update top-level version and packages[0].version in server.json.
• Update top-level version and packages[0].version in manifest.json.
• Add a changeset: pnpm changeset at repo root.
• Run pnpm build && pnpm test && pnpm typecheck in this package.
• Run pnpm smoke:pack in this package — it packs, installs the tarball into a clean directory and checks tools/list and get-spec over stdio; it must print PASS before you publish.

2. Publish to npm

• pnpm publish --access public --no-git-checks from this directory.
• Verify: npm view @mobile-reality/mdma-mcp version mcpName — both should match.

3. Publish to the MCP Registry

• Ensure mcp-publisher is authenticated: mcp-publisher login github (re-auth if tokens expired).
• mcp-publisher publish from this directory.
  • Alternative: run the "Publish to MCP Registry" workflow from the Actions tab on main after the npm publish. Interactive mcp-publisher login github fails when the organization restricts OAuth apps; the workflow uses GitHub OIDC instead.
• Verify: curl "https://registry.modelcontextprotocol.io/v0.1/servers?search=io.github.MobileReality/mdma" shows the new version.

Do not commit .mcpregistry_github_token / .mcpregistry_registry_token — they are in .gitignore. GitHub's push protection will block the push anyway; this is a belt-and-braces reminder.

4. Tag the release

git tag '@mobile-reality/mdma-mcp@<version>'
git push origin '@mobile-reality/mdma-mcp@<version>'

5. Build a fresh MCPB bundle (only if submitting a Desktop Extension update)

pnpm's virtual store (.pnpm/) gets stripped by mcpb pack, so you must build the bundle from a clean npm-installed directory or transitive deps (e.g. ajv) will be missing.

Output: <name>-<version>.mcpb. Test-install in Claude Desktop, then attach as a GitHub Release asset.

6. Glama — if tool descriptions or Dockerfile config changed

• If you added / renamed / changed descriptions of tools: Glama's Quality score will re-evaluate on its next periodic scan. No manual trigger.
• If packages[0].version bumped: go to the Glama admin page → update Build steps (npm install -g @mobile-reality/mdma-mcp@<version>) → Deploy → Make Release.

7. Downstream awareness

• Update the MCP tools table in the root README.md if tools were added / renamed / removed.
• Update this package's own tools table (above) the same way.
• If tools changed: update the MCP.so listing, which is owned by another account (see the MCP.so row in Distribution venues).
• If a breaking change: note in the changeset; update consumers of createMdmaMcpServer() if any.

Troubleshooting

MCP Registry publish fails with 403 Forbidden

If the error says permission to publish: io.github.gitsad/*, io.github.MobileReality/*. Attempting to publish: io.github.mobilereality/mdma (lowercase mismatch): the registry is case-sensitive and your mcpName / server.json name must exactly match GitHub's canonical MobileReality capitalization. Fix both files and republish to npm (versions on npm are immutable).

If the error says permission to publish: io.github.gitsad/* (org missing entirely): your MobileReality GitHub membership is private. Make it public at https://github.com/orgs/MobileReality/people, then mcp-publisher logout && mcp-publisher login github to refresh the JWT.

MCPB .mcpb crashes on install in Claude Desktop

Usually "missing module" errors in the Developer tab logs. Cause: pnpm's nested .pnpm/ virtual store got stripped at pack time, so transitive deps are missing. Fix: build the bundle from a clean npm-installed directory (see step 5 above). Do not run mcpb pack directly against packages/mcp/node_modules.

Secrets leaking into the bundle

mcpb pack does not respect .gitignore. Any .mcpregistry_*_token file next to the manifest at pack time gets zipped into the .mcpb. Always delete these before packing, and prefer the /tmp/mcpb-build workflow above which has no tokens in its directory.
