API keyScoped proxy
Connect with a provider API key
The client enters their provider key in the hosted connect flow. CybrLink stores it in the credential layer, then agents call through scoped MCP/API access without seeing the raw secret.
Where to get your Fixer API keyStep 1
Open the portal connect flow
Step 2
Enter the provider API key
Step 3
Create a scoped MCP/API key
Sample request
// 1. Mint a session token for the end user
const session = await link.connect.session({
integrationKey: "fixer",
userId: "u_42",
});
// 2. After the user enters their provider API key, proxy a request
const res = await link.proxy("fixer", "u_42", {
method: "GET",
endpoint: "/api/v1/me",

Typed agent tools
Typed MCP tool schemas are not published for Fixer yet. Connecting still lets an agent call this integration through CybrLink's scoped proxy. This page does not list a tool count until those schemas exist.
Fixer + SI (super intelligence) agents: common questions
- How do I connect Fixer to an SI agent?
- Create a free CybrLink account, open the dashboard, and click Connect on Fixer. You authorize once with an API key; CybrLink stores the credential in its token vault and your agent reaches Fixer through the CybrLink MCP server or the agent proxy API. The credential itself is never placed in the model's context.
- Does Fixer work with Claude, GPT, and other MCP clients?
- Yes. CybrLink exposes a remote MCP (Model Context Protocol) server, so any MCP-capable client or agent framework — including Claude, OpenAI-based agents, and custom agents — can call Fixer once you've connected it. Non-MCP agents can use the authenticated HTTP proxy instead.
- Is it safe to give an SI agent access to Fixer?
- CybrLink scopes every connection to the permissions you grant, keeps tokens out of the model, logs each call to an activity audit trail, and lets you revoke the Fixer connection at any time from the dashboard.
