Feather is then searchable from wherever you are already working. ### Claude Install the official Streamline connector from the Claude directory. #### Step 1: Add the connector Open Streamline in the Claude directory and click Connect. [Add to Claude](https://claude.ai/directory/connectors/streamline-icons) **Using Claude Code?** Run this in your terminal, then run /mcp in Claude Code and pick streamline. ``` claude mcp add --transport http streamline https://public-api.streamlinehq.com/mcp ``` #### Step 2: Sign in Sign in with your Streamline account to authorize access. ### Cursor Install Streamline in Cursor with one click. #### Step 1: Add the server Click install to open Cursor and add the Streamline MCP. [Install in Cursor](cursor://anysphere.cursor-deeplink/mcp/install?name=streamline&config=eyJ1cmwiOiJodHRwczovL3B1YmxpYy1hcGkuc3RyZWFtbGluZWhxLmNvbS9tY3AifQ%3D%3D) **Prefer to add it manually?** Add this to your \~/.cursor/mcp.json file. ``` { "mcpServers": { "streamline": { "url": "https://public-api.streamlinehq.com/mcp" } } } ``` #### Step 2: Sign in Sign in with your Streamline account to authorize access. ### ChatGPT In ChatGPT, go to Settings, then Plugins, then MCPs, and click Add Server. Fill the form with these three values. #### Step 1: Fill the form Name, type, and URL, exactly as below. ``` Name Streamline Type Streamable HTTP URL https://public-api.streamlinehq.com/mcp ``` #### Step 2: Save and authenticate Click Save, then click Authenticate and follow the steps. ### Antigravity The Antigravity CLI and the Antigravity IDE read one config file, so you set this up once and both pick it up. #### Step 1: Add the config Put this in \~/.gemini/config/mcp\_config.json. A headers block is unnecessary, because Streamline supports dynamic client registration and Antigravity discovers the OAuth endpoints on its own. ``` { "mcpServers": { "streamline": { "serverUrl": "https://public-api.streamlinehq.com/mcp" } } } ``` #### Step 2: Authenticate Open Agent Settings, go to the Customizations tab, and click Authenticate next to streamline. Sign in, then copy the authorization code back into the settings panel and click Submit. ### Others Most MCP-compatible clients accept a JSON configuration block. Streamline supports dynamic client registration, so there are no client credentials to configure. #### Step 1: Add the configuration The first time the client connects it opens your browser to sign in and authorize access. ``` { "mcpServers": { "streamlineMCPServer": { "name": "Streamline MCP Server", "url": "https://public-api.streamlinehq.com/mcp" } } } ``` #### Step 2: Use an API key if the client has no OAuth Add your Streamline API key as a header instead, replacing YOUR\_API\_KEY\_HERE. ``` { "mcpServers": { "streamlineMCPServer": { "name": "Streamline MCP Server", "url": "https://public-api.streamlinehq.com/mcp", "headers": { "X-API-Key": "YOUR_API_KEY_HERE" } } } } ``` To confirm any of them connected, ask your tool to search for a dog icon. The results should come back from Streamline. ## Feather has 287 free icons in one line style Created by Cole Bemis, free and open source, hosted on Streamline and searchable through the MCP. * **Feather**: [287 free icons](https://www.streamlinehq.com/icons/feather-line) ## Core is the line set that pairs with it 998 free, 5,615 pro icons per style.

Streamline hosts all 287 of them, and the MCP searches them from inside the tool you are already working in. Setup is one block to paste and a browser sign-in. The server is hosted, so there is nothing to install locally and the tool list stays current on Streamline's side. ## Master The Craft Everything Streamline draws is made in-house by one team of veteran icon designers. That's how we get true consistency. We go back to older icons and improve them. Ultimate has been improved five times since it originally launched. ## Depth Over Breadth We go deep. Streamline builds massive, complete icon sets designed to cover every use case you'll ever need. Feather covers the common interface ground, and the same MCP carries the rest. You won't discover a gap, then end up drawing the icons yourself or mixing sets that never quite match. The sets don't compete. They add up to one coherent icon library. ## Frequently asked questions Quick answers about using Feather icons through an MCP. ### What is the Feather Icons MCP? The Feather Icons MCP is Streamline's MCP server, which serves Feather along with every other set it hosts. One MCP covers Feather and the rest of the library alongside it. ### How do I connect it? Pick your tool in the steps above and paste the block it gives you, then sign in through the browser. The same instructions live on [streamlinehq.com/mcp](https://www.streamlinehq.com/mcp). ### How many Feather icons are there? 287, free, in one line style. Cole Bemis created Feather and maintains it at [feathericons.com](https://feathericons.com). ### Is Feather free to use? Yes. Feather is open source and free on Streamline. Each open-source set follows its own license, so check Feather's before shipping commercially. ### What formats and sizes come back? SVG or PNG, at any size from 1 to 4096 pixels. The same call takes colors, a background color, and a stroke width. ### Can I reach other sets on the same MCP? Yes. Scope the search wider and Core, Flex, Sharp and Plump answer on the same MCP, with no extra setup. ### Can I connect other icon sets the same way? Yes. The same server reaches every set Streamline hosts. See [the icons MCP page](/icons-mcp.md) for the full picture.
