Anthropic Connectors Directory — tdmcp submission spec

The "Claude marketplace" is the Anthropic Connectors Directory, surfaced in Claude Desktop at Settings → Extensions → Browse extensions ("Anthropic-reviewed tools"). There are two submission paths with separate forms — picking the wrong one wastes a ~2-week review cycle.

Path decision — tdmcp is a Desktop Extension (MCPB)

Path	For	tdmcp?
Remote MCP server (internet-hosted, OAuth 2.0) → MCP Directory form	SaaS-style connectors Claude reaches over the network	NO
Desktop Extension (local MCP server bundled as MCPB) → Desktop extension form	Local servers that run on the user's machine	YES

Why local: tdmcp is a Node/stdio server that talks to a Python bridge running inside TouchDesigner at 127.0.0.1:9980. It cannot be hosted remotely — it must run next to TD on the artist's machine. So OAuth/hosting requirements do not apply; ignore them. Submit via the Desktop extension form (linked from the official submission docs page).

.dxt was renamed to .mcpb (MCP Bundle). Existing .dxt still installs, but new submissions should ship .mcpb. See the mcpb-bundle skill.

Approval gates (these cause rejection)

Gate	Requirement	tdmcp status
Privacy policy	Present + complete. Missing = immediate rejection.	TODO — docs-author writes it (local-only ⇒ short)
Tool annotations	Every tool has safety hints (readOnlyHint/destructiveHint). Missing = ~30% of all rejections.	PASS — all tools annotated (verified in src/tools/**)
Production-ready	Not beta. Stable, versioned, installable.	PASS — v0.3.0 on npm + MCP registry
Public docs URL	Setup + usage docs.	PASS — https://pantani.github.io/tdmcp/
Data-handling statement	What data is handled and where it goes.	TODO — trivial (see below)
Branding	Logo / icon.	PASS — docs/public/logo-400.png (400×400) + favicon
Installable bundle	A valid .mcpb.	TODO — bundle-engineer migrates .dxt→.mcpb

The local-only compliance story (reuse everywhere)

tdmcp's compliance answers are simple because of what it is — state it plainly:

• Runs entirely on the user's machine. No accounts, no sign-in, no cloud.
• The MCP server only makes HTTP calls to the user's own TouchDesigner bridge on 127.0.0.1:9980 (configurable host/port). No other network egress.
• Collects no user data, no telemetry, no analytics, sends nothing to the author or any third party.
• The user's AI client (Claude/Cursor/Codex) processes prompts under that client's privacy policy — tdmcp adds no data collection of its own.
• Security note worth stating: the bridge executes Python inside TD and listens on 9980; for untrusted networks the user sets TDMCP_BRIDGE_TOKEN / TDMCP_BRIDGE_ALLOW_EXEC=0 (already documented in the architecture docs).

This is the basis for both the privacy policy page and the form's data/compliance fields.

Form field map (Desktop extension form)

For each field: the canonical answer or who drafts it. Known repo facts are filled.

Field	Answer / source
Name	tdmcp
Display name	TouchDesigner (tdmcp) (from dxt/manifest.json)
Tagline (one-liner)	docs-author — reuse docs/index.md hero
Description	docs-author — reuse what-is-tdmcp + README; mention 100+ tools, knowledge base, create→verify→preview
Use cases	docs-author — VJ/live audiovisual, generative art, audio-reactive, projection mapping (see prompt-cookbook)
Category	Creative / media tools
Transport	stdio (Claude Desktop spawns the local server)
Auth	None (local)
Tools list + annotations	architect derives from src/tools/**; each tool's title/readOnlyHint/destructiveHint
Data handling / compliance	the local-only story above
Privacy policy URL	the new page docs-author publishes (e.g. https://pantani.github.io/tdmcp/privacy)
Public docs URL	https://pantani.github.io/tdmcp/
Repo	https://github.com/Pantani/tdmcp
npm	@dpantani/tdmcp
MCP registry id	io.github.Pantani/tdmcp
License	MIT (verify LICENSE)
Logo / branding	docs/public/logo-400.png, favicon
Bundle	tdmcp.mcpb (from the migrated build)
Support channel	NEEDS HUMAN INPUT — GitHub Issues URL is the likely answer; confirm
Test account credentials	NEEDS HUMAN INPUT — likely N/A (no auth); note "local tool, no account"
Production-ready confirmation	Yes — v0.3.0

Distinguish from what's already done

• MCP Registry (io.github.Pantani/tdmcp, active) is the open registry — already done, feeds PulseMCP etc. It is not the Anthropic directory.
• desktopextensions.com and awesome-* lists are community discovery, not the official directory.
