Connectors Directory Spec

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.
