name: connectors-directory-spec description: Authoritative reference for submitting tdmcp to the Anthropic Connectors Directory as a Claude Desktop Extension (MCPB). Use whenever drafting, checking, or fixing the submission — it defines the two submission paths, why tdmcp is a Desktop Extension (never a remote connector), every form field, the rejection-causing gates, and the local-only compliance story. Read this before writing any submission deliverable.

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.
