Pollinations Multimodal MCP Server

A Model Context Protocol (MCP) server for the Pollinations APIs that enables AI assistants like Claude to generate images, text, and audio directly. This server follows the "thin proxy" design principle, focusing on minimal data transformation and direct communication through stdio.

Features

  • Generate image URLs from text prompts

  • Generate actual images and return them as base64-encoded data

  • Generate text responses from text prompts

  • Generate audio (text-to-speech) from text prompts

  • List available image and text generation models

  • STDIO transport for easy integration with MCP clients

  • Simple and lightweight

  • Compatible with the Model Context Protocol (MCP)

System Requirements

  • Node.js: Version 14.0.0 or higher

    • For best performance, we recommend Node.js 16.0.0 or higher

    • Node.js versions below 16 use an AbortController polyfill

Quick Start

The easiest way to use the MCP server:

# Run directly with npx (no installation required)
npx @pollinations/model-context-protocol

If you prefer to install it globally:

# Install globally
npm install -g @pollinations/model-context-protocol

# Run the server
pollinations-mcp

Transport

The MCP server exclusively uses STDIO transport, which is ideal for local integrations and command-line tools:

# Run with STDIO transport
npx @pollinations/model-context-protocol

For MCP clients, connect using:

npx supergateway --stdio -- pollinations-mcp

Claude Desktop Integration

To install the MCP server in Claude Desktop:

# Run the installation script
npx @pollinations/model-context-protocol install-claude-mcp

This script will automatically:

  • Find the Claude Desktop configuration file for your OS

  • Add the Pollinations MCP server to the configuration

  • Configure it to use npx for easy updates

After installation, restart Claude Desktop and you can use commands like:

Generate an image of a sunset over the ocean using the Pollinations API.

Alternative MCP Implementations

  • MCPollinations: A community-maintained alternative MCP server supporting similar capabilities. Available at GitHub and NPM.

Troubleshooting

"AbortController is not defined" Error

If you encounter this error when running the MCP server:

ReferenceError: AbortController is not defined

This is usually caused by running on an older version of Node.js (below version 16.0.0). Try one of these solutions:

  1. Update Node.js (recommended):

    • Update to Node.js 16.0.0 or newer

  2. Use our polyfill (automatic in version 1.0.6+):

    • Update to the latest version of the package:

    npm install -g @pollinations/model-context-protocol@latest
# or run with npx
npx @pollinations/model-context-protocol@latest

  3. Install AbortController manually:

    • If for some reason the polyfill doesn't work:

    npm install node-abort-controller

Check Your Node.js Version

To check your current Node.js version:

node --version

If it shows a version lower than 16.0.0, consider upgrading for best compatibility.

Available Tools

The MCP server provides the following tools:

Content Generation

  1. generateImageUrl - Generates an image URL from a text prompt

  2. generateImage - Generates an image and returns it as base64-encoded data

  3. respondAudio - Generates an audio response to a text prompt

  4. sayText - Generates speech that says the provided text verbatim

  5. generateText - Generates text from a prompt using text models

  6. listModels - Lists available models for image or text generation

    B3.2/5.0

    Scored across 12 tools

    Disambiguation4/5

    Most tools have distinct purposes, but there is some potential confusion between generateImage and generateImageUrl (both generate images but return different outputs) and between respondAudio and sayText (both produce audio but with different input approaches). The descriptions help clarify, but an agent might need to carefully choose between these pairs.

    Naming Consistency4/5

    The naming follows a consistent verb_noun pattern (e.g., generateImage, listAudioVoices, updateDomains) with minor deviations like checkAuthStatus (which could be checkAuth or getAuthStatus) and startAuth (which could be initiateAuth). Overall, it's readable and mostly predictable.

    Tool Count5/5

    With 12 tools, the count is well-scoped for a multimodal server covering authentication, image generation, text generation, audio generation, and model listing. Each tool serves a clear purpose without feeling excessive or insufficient for the domain.

    Completeness4/5

    The toolset covers key areas like authentication, content generation (image, text, audio), and model management, but there are minor gaps such as lacking tools for deleting or managing generated content (e.g., deleteImage, updateText) and no tool for checking usage or quotas. However, agents can work around these for core workflows.
