Auphonic (via Zapier MCP)
Auphonic's automated audio post (loudness, leveling, denoise) reachable through Zapier MCP.
What it does
Auphonic is the de facto automated audio post-production service — loudness normalization to broadcast specs, speech leveling, denoising, de-essing, and filler-word cutting. It has no first-party MCP server; Zapier's hosted MCP exposes Auphonic actions to agents, making it the verified route for agent-driven dialogue cleanup and final-mix loudness compliance.
Connect
https://mcp.zapier.com/api/v1/connectRemote headers required: Authorization. Use a client that can attach custom MCP headers; this listing has no local stdio fallback.
Connection is set up through the vendor's flow — follow the official connect instructions.
Field notes
Docs link moved: the old help.zapier.com article 301s to docs.zapier.com, and the page that actually specifies the wire format is now /mcp/overview/how-connections-work. The endpoint is unchanged and still live — one shared Streamable HTTP URL, https://mcp.zapier.com/api/v1/connect (401 unauthenticated on 22 Sep 2026), Streamable HTTP only, with `Authorization: Bearer <token>` as the documented form; the query-string variant ?token= still works and Zapier's own docs now warn it ends up in logs and shell history. The token is minted per MCP server you create at mcp.zapier.com after connecting Auphonic, is shown exactly once, and grants whatever tools that server exposes, so treat it as a password; there is no published CLI one-liner, so add it through your client's header config. New since August: servers default to 'agentic mode', which exposes 16 static meta-tools (discover_zapier_actions, enable_zapier_action, auto_provision_mcp and so on) and lets the agent enable actions mid-conversation — convenient interactively, unpredictable in a pipeline. Switch the server to managed mode at mcp.zapier.com if you want a fixed toolset with pre-filled fields. Still a generic Zapier gateway rather than a dedicated audio MCP: the surface is two Auphonic actions — Create Production and its trigger — so an agent gets 'submit a job with a preset', not per-parameter mastering control, and every call routes your audio through a third integration layer. Tool names stay null because Zapier mints them from the actions you enable rather than publishing a fixed list — read tools/list once connected. Auphonic gives 2 free processing hours per month, and its own docs at auphonic.com/help still make no mention of MCP. For measured loudness compliance without the middleman, REAPER MCP in this directory does analyze_loudness plus apply_limiter locally, and the AudioLab entry meters a finished file against named delivery targets; ElevenLabs isolate_audio remains the nearest one-shot dialogue denoiser.
