Higgsfield MCP: How to Connect Higgsfield to Claude in 2026

To connect Higgsfield to Claude, open Claude's Connectors settings, add a custom connector named Higgsfield, paste the address mcp.higgsfield.ai/mcp and sign in with your Higgsfield account. There is no API key. The real conditions sit on the Higgsfield side: the connector needs an active paid plan, so the cheapest way in is Starter at $19 a month, and every image or clip Claude starts spends ordinary plan credits at standard rates. Unlimited windows and free generations never apply through it. For anyone who briefs campaigns in chat, that is a fair deal. If you bought Plus or Ultra mainly for its Unlimited days, keep generating those clips on the website.

What your Higgsfield account needs first

Higgsfield's help center is plain about the gate: connecting MCP requires an active paid Higgsfield subscription, on top of whatever your Claude plan requires.^[1] The Free plan cannot connect at all. Starter at $19 a month, billed monthly or yearly, brings 270 credits a month, but it covers selected models only: no Seedance 2.5, no Veo 3.1, and Kling 3.0 at 720p only. If you want Claude to direct Seedance 2.5 shots, the lowest plan that includes the model is Plus, at $59 a month or $47 a month billed yearly, with 1,200 credits a month.

There is no separate MCP balance. Claude draws on the same credits you spend on higgsfield.ai, and Higgsfield states that MCP always uses credits, because Unlimited access and free generations work only on the website.^[2] This matters most on Plus billed yearly, whose 7-day Unlimited window includes Seedance 2.5 at 720p on higgsfield.ai only, in a slower standard queue, for personal use. Ask Claude for the same shot and it costs credits. At Higgsfield's posted rate a 5-second Seedance 2.5 clip at 720p costs 35 credits, so Plus covers about 34 such clips a month, roughly $1.72 each on Plus billed monthly, by our arithmetic.

By our arithmetic, moving from Starter to Plus monthly adds $40 a month for 930 more credits and unlocks every model on the pricing table. In clip terms, Starter's credits cover about 36 Kling 3.0 clips of 5 seconds at 720p a month and Plus about 160, one take each. Expect several takes per keeper. Subscription credits also reset every cycle and unused ones are lost; our Higgsfield pricing guide covers rollover, refunds and packs.

Connecting Higgsfield in Claude, step by step

The setup takes a few minutes and happens entirely inside Claude's settings, with a browser sign-in at the end. Have your Higgsfield login ready, whether that is email or the Google, Apple or Microsoft account you signed up with, and sign in to the account that holds the paid plan. Higgsfield's older posts label the menu Settings and its newer posts call it Customize; the Connectors page behind it is the same.

1. In Claude, open Settings (or Customize), then Connectors.
2. Choose Add custom connector and name it Higgsfield.
3. Paste mcp.higgsfield.ai/mcp, with the https prefix, as the connector URL.
4. Click Connect, sign in to your Higgsfield account and authorize the connection.
5. Start a chat and check that the Higgsfield connector is switched on for it.

That last step catches most first-time users. Higgsfield's launch post notes that the connector may still need enabling in each conversation, so if Claude ignores your video request, check first that the connector is switched on for that chat. Use only the official address. Higgsfield's help center says a connector pointing anywhere else is not Higgsfield, and the setup page lives at higgsfield.ai/mcp. Finished work lands in your Assets library, tagged with the MCP source, typically within 60 seconds of the job completing, so check there first if the chat shows nothing.

What Claude can reach, and where it stops

The reach is wide. Higgsfield's posts say the connector exposes 30+ models, including Soul, Cinema Studio, Seedance 2.5 and Kling, with images up to 4K. The MCP page states video clips of up to 15 seconds per generation. Longer finished pieces come from Shorts Studio, at 15 seconds to 2 minutes, and Content Factory, at 15 seconds to 5 minutes, both runnable through MCP. The help center adds Kling 3.0 Motion Control, upscaling, background removal, outpaint, Soul characters and Elements, voiceover, voice cloning, dubbing, Ad Multiplier, Genjutsu in all three modes, and Marketing Studio presets such as Hook Multiplier and Ad Recreator.

Attachments are the gap people hit first. Claude cannot pass images you drop into the chat to Higgsfield. References go through a Higgsfield upload window that the agent opens, or through a pasted image URL. Kling 3.0 Motion Control needs both a character image and a motion reference video. The full Marketing Studio template library stays on the website, with only a smaller preset set over MCP. Voice clones are limited to five per workspace by default. You must hold rights and consent from anyone whose face or voice goes into your inputs.

Claude is also the fuller chat route. In ChatGPT, Higgsfield connects through its official plugin, installed from the ChatGPT plugins page by searching for Higgsfield and signing in, but audio generation and the Website Building skill are missing there. Both work in Claude, Cursor and CLI agents. Cursor connects through its marketplace instead of a custom connector. So if your brief includes voiceovers or dubbing and you want to stay in a chat window, Claude is the route that covers it.

Claude Code, Katana and the Bridge

Pick the route by where you work. The chat connector suits briefs and campaign ideas, Claude Code suits scripted batches, Katana suits remixing a reference edit with your own photos, and the Bridge suits editing inside Adobe or Blender. All four sign in through your Higgsfield account rather than a key, and none of them touches the separate API balance. The table sorts them before the details.

In Claude Code you skip the connector and use the open-source CLI, which the agent can install itself. It arrived in May 2026 and also works with Cursor, Codex, OpenClaw and Hermes. Higgsfield positions the CLI for coding agents because it costs fewer tokens, and MCP for chat agents because it exposes every tool with free parameter choice. The help center's sequence is three commands:^[3]

• npm i -g @higgsfield/cli (curl and Homebrew also work)
• higgsfield auth login, which opens a browser sign-in
• npx skills add higgsfield-ai/skills, which adds the generate, soul and product-photoshoot skills

The command is higgsfield, aliased higgs, and it reaches 35+ models and tools on plan credits. The Skills hub lists 35 skills for Claude. Unlimited windows, which cover named models for a set number of days on higgsfield.ai only, never apply here. A CLI run is billed exactly like a web generation at standard rates, so a loop that renders twenty variants charges twenty times.

Katana, added in October 2026, is a Higgsfield skill for Claude that rebuilds a reference edit with up to five of your own photos, on a paid plan. Claude shows the exact credit cost before each generation, and corrections that need new generations cost more.^[4] A shared Katana preset takes a 3 to 30 second video and up to 40 images. Photos attached in chat are not passed, and Instagram or TikTok profile links are not accepted.

The Bridge is a second custom connector, named Higgsfield Bridge, at bridge.higgsfield.ai/mcp. Once the Higgsfield plugin is installed, it lets Claude drive the Premiere Pro, After Effects and Blender plugins. The plugins need no extra subscription and run on plan credits. The Production Skills Bundle of September 2026 adds 11 Claude workflows for Blender, Adobe apps, TouchDesigner and DaVinci Resolve Studio. Claude Desktop must run on the same computer as that software.

Keeping an agent's spending in check

There is no hard credit cap per MCP session. A spending limit you type into the chat is an instruction to the agent, nothing more. Higgsfield's terms make you responsible for everything an agent generates through your account. Every completed generation is charged, including takes you never use, and a batch of two to four outputs charges each one. Higgsfield's own post puts a usable clip at three to five generations, so the cost per keeper runs well above the price of one take.

Three habits keep that in check. Ask Claude to state the credit cost and wait for your yes before each job, the way Katana already does. Draft on cheaper models: on the pricing table Kling 3.0 runs about 7 credits per 5 seconds at 720p against about 22 for Seedance 2.0. Watch the Assets tab rather than the chat. Credits for most failed generations come back automatically within minutes, but Grok is charged the moment it starts.

Heavy agent use eventually raises the plan question. Starter cannot use Auto-Refill, which tops up at $1 for 18 credits on higher plans. By our arithmetic, Plus at $59 a month plus a $90 refill comes to $149 for 2,820 credits, while Ultra at $129 a month brings 3,000. Once you would refill Plus by $70 or more a month, Ultra gives more for less. Refill and pack credits expire after 90 days.

The connector is not the API. MCP, CLI and plugins sign in with your Higgsfield account and spend plan credits; the API uses its own key and a separate prepaid dollar balance, with a $5 minimum top-up, and no subscription includes it. For steady volume a paid plan's credits cost less per clip than API list prices. The API suits pipelines that need no subscription and funds that last a year, covered in our Higgsfield API guide.

The bottom line

Connecting Higgsfield to Claude is the easy part: one official URL, one sign-in, no key. The decision is about credits. Every generation through the connector, the CLI, Katana or the Bridge spends your plan balance at standard rates, and nothing caps a session except your own instructions. Starter at $19 a month connects, with no Seedance 2.5 and no Veo 3.1 on that plan. Plus is the realistic floor for agent-led video. Upload references through Higgsfield, ask for costs before each job, and save the time-limited Unlimited windows on named models for higgsfield.ai, where they run in the slower standard queue.
