Claude custom connectors make it possible to connect Claude to external tools, APIs, and data sources.
In this article, I’ll show a practical example: connecting Claude to an SVG icon search engine so it can search for icons and return usable SVG assets directly inside a development workflow.
The example uses SVGIcons.com, an SVG icon search engine I’m building for developers, but the same pattern can be applied to many other developer tools.
Why connect Claude to an SVG icon search engine?
When building an application, website, dashboard, landing page, or documentation page, developers often need icons quickly.
The usual workflow looks like this:
- Open an icon website.
- Search for the right icon.
- Compare visual options.
- Copy or download the SVG.
- Paste it into the project.
- Adjust size, color, classes, or framework-specific syntax.
That works, but it interrupts the development flow.
With a Claude custom connector, the workflow can become more direct:
“Find me a simple outline icon for user settings.”
“Give me an SVG icon for database sync.”
“Find icons related to authentication, security, and login.”
“Return a clean SVG I can use in a React component.”
Instead of switching context, Claude can call the connector and retrieve relevant SVG icons from the search engine.
What is a Claude custom connector?
A Claude custom connector allows Claude to interact with an external service through an MCP server.
MCP stands for Model Context Protocol. It provides a standard way for AI assistants to connect to tools and data sources.
In practice, this means Claude can do more than generate text. It can call tools such as:
- Search engines
- Internal documentation systems
- Databases
- File repositories
- SaaS APIs
- Design asset libraries
- Developer utilities
For this example, the external tool is an SVG icon search engine.
The use case: searching SVG icons from Claude
SVGIcons.com provides a large searchable database of SVG icons.
The goal of the connector is simple:
- Claude receives a user request.
- Claude calls the SVG icon search tool.
- The connector searches SVGIcons.com.
- Claude receives matching icon results.
- Claude can present the most relevant icons to the user.
For example, a developer could ask:
Find an SVG icon for a settings panel.
Claude can then use the connector to search for icons related to:
settings
preferences
sliders
controls
configuration
Then it can return a relevant SVG icon or suggest several options.
Why this is useful for developers
This kind of connector is useful because icons are often needed during small, frequent development tasks.
For example:
- Building a sidebar navigation
- Creating a settings page
- Adding buttons to a SaaS dashboard
- Designing empty states
- Improving documentation pages
- Creating landing page feature blocks
- Building prototypes
- Generating React, Vue, or Svelte components with inline SVG
Instead of manually searching every time, Claude can become part of the asset discovery workflow.
Example prompts
Once the connector is available, you can ask Claude things like:
Find a clean SVG icon for a user profile button.
Search for icons related to analytics and charts.
Find three SVG icons that could represent API integration.
Give me an SVG icon for dark mode and adapt it for a React component.
Find a simple icon for file upload and return the raw SVG.
This is especially useful when Claude is already helping you write code.
For example, you could ask:
Create a settings page layout in React and use an SVG icon for each section.
Claude can then combine code generation with icon search.
Example workflow
A possible workflow could look like this:
User:
I’m building a SaaS dashboard. Find icons for Users, Billing, API Keys, and Settings.
Claude:
I’ll search for suitable SVG icons for each section.
The connector can then search the icon database and return matching results.
Claude can organize them like this:
Users: user, team, profile
Billing: credit-card, invoice, wallet
API Keys: key, code, terminal
Settings: gear, sliders, controls
Then Claude can help generate the UI code:
const navigationItems = [
{
label: "Users",
href: "/users",
icon: UserIcon,
},
{
label: "Billing",
href: "/billing",
icon: BillingIcon,
},
{
label: "API Keys",
href: "/api-keys",
icon: ApiKeyIcon,
},
{
label: "Settings",
href: "/settings",
icon: SettingsIcon,
},
];
The key idea is not just icon search. It is icon search inside the development context.
Why SVG is a good fit for AI-assisted workflows
SVG works especially well in AI-assisted development because it is text-based.
That means Claude can:
- Read SVG markup
- Modify attributes
- Change dimensions
- Adjust colors
- Add CSS classes
- Convert SVG into components
- Inline icons directly in generated code
For example, Claude can transform a raw SVG into a React component:
export function SettingsIcon(props: React.SVGProps<SVGSVGElement>) {
return (
<svg
viewBox="0 0 24 24"
fill="none"
aria-hidden="true"
{...props}
>
<path
d="..."
stroke="currentColor"
strokeWidth="2"
strokeLinecap="round"
strokeLinejoin="round"
/>
</svg>
);
}
This makes SVG icons much easier to integrate than binary image formats.
What the connector needs to expose
A useful SVG icon connector should expose a small set of clear tools.
For example:
search_icons(query)
Search for icons matching a text query.
get_icon(id)
Retrieve a specific SVG icon.
get_related_icons(id)
Find icons visually or semantically related to a selected icon.
convert_icon(format)
Convert the SVG into a framework-friendly format, such as React TSX, Vue, or Svelte.
The connector does not need to be complex. It just needs to give Claude structured access to the icon search engine.
Example connector behavior
A search request could look like this:
{
"query": "database sync",
"limit": 5
}
The connector could return structured results:
[
{
"name": "database-sync",
"category": "development",
"svg": "<svg>...</svg>",
"url": "https://svgicons.com/..."
},
{
"name": "cloud-database",
"category": "cloud",
"svg": "<svg>...</svg>",
"url": "https://svgicons.com/..."
}
]
Claude can then decide how to present the results depending on the user’s request.
A practical example with SVGIcons.com
For this example, the connector is associated with SVGIcons.com.
SVGIcons.com is designed as a search engine for SVG icons. The goal is to help developers find production-ready SVG icons quickly and reuse them in websites, applications, documentation, and design systems.
A connector makes this more powerful because it lets Claude search the icon database during a conversation.
For example:
Find me a minimal SVG icon for a command palette.
Claude can search the icon database and return relevant icon suggestions without forcing the developer to leave the chat.
This pattern applies beyond icons
The interesting part is not limited to SVG icons.
The same MCP connector pattern could be used for many developer resources:
- Component libraries
- Internal design systems
- Code snippets
- Documentation
- API references
- Brand assets
- UI templates
- Color palettes
- Product screenshots
Any structured resource that developers search repeatedly could become more useful when connected to Claude.
SEO and developer documentation use case
There is also an interesting documentation angle.
If a developer tool exposes a custom connector, it is useful to create documentation showing:
- What the connector does
- How to install or configure it
- Example prompts
- Supported tools
- Example responses
- Security and privacy details
- Limitations
This helps both human developers and AI assistants understand how to use the tool.
For SVGIcons.com, this fits naturally with developer-focused pages such as:
Final thoughts
Claude custom connectors are a practical way to bring external developer tools directly into the AI workflow.
For SVG icons, this means Claude can help developers search, retrieve, adapt, and integrate icons without leaving the coding context.
The same idea can be applied to many other developer resources.
If you are building a developer tool, exposing it through an MCP connector can make it much easier for AI assistants to use it effectively.
And if your tool provides searchable assets, documentation, or structured data, a connector can turn it into something Claude can actively work with instead of something users have to search manually.
