MCP-first launch

MCP setup in 5 minutes

Use the published stdio package for local editor integrations, or call the hosted Streamable HTTP endpoint with Bearer auth. Free keys get company lookup, connector search/fetch, rankings, and direct relationships; Pro keys add deeper graph, changes, and analysis scopes.

Set your API key

All MCP entrypoints expect the same secret. Export it once for local tooling or paste it into the app-specific config.

export REJSTRIK_API_KEY=<YOUR_API_KEY>

Hosted HTTP endpoint

Remote clients can connect directly to https://rejstrik.ai/mcp using Bearer auth.

curl https://rejstrik.ai/mcp \
  -H "Authorization: Bearer <YOUR_API_KEY>" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

Claude Desktop

Add the rejstrik server to your Claude Desktop JSON config.

{
  "mcpServers": {
    "rejstrik": {
      "command": "npx",
      "args": ["-y", "@rejstrik/mcp"],
      "env": {
        "REJSTRIK_API_KEY": "<YOUR_API_KEY>"
      }
    }
  }
}

Claude Code

Claude Code supports stdio MCP via claude mcp add.

claude mcp add --transport stdio rejstrik \
  --env REJSTRIK_API_KEY=<YOUR_API_KEY> \
  -- npx -y @rejstrik/mcp

ChatGPT developer mode

Use the hosted remote MCP endpoint. The server exposes connector-compatible search and fetch tools, plus richer developer tools for MCP clients that allow them.

Remote MCP URL: https://rejstrik.ai/mcp
Auth header: Authorization: Bearer <YOUR_API_KEY>
Connector tools: search, fetch
Developer tools: lookup_company, search_companies, get_relationships

What the stdio bridge does

The npm package authenticates against the hosted Rejstrik AI MCP endpoint with your API key, so users do not need a local clone of the API service.

  • Package: @rejstrik/mcp
  • Environment variable: REJSTRIK_API_KEY
  • Optional override: REJSTRIK_API_BASE
