Free discovery · no account · no API key

Let your agent do the finding.

Paste into your AI agent
Read https://toolcargo.com/agents.txt, then find remote MCP server URLs for my task and inspect their transport, headers and URL-template variables before helping me connect. Ask me what I want to do first.

Or add https://toolcargo.com/mcp as a Streamable HTTP MCP server. Discovery is free and needs no account.

Compare task fit, publisher, permissions and a small acceptance test with the MCP server selection guide.

Remote URLs go into your client's MCP settings. Local packages need a compatible runtime. Check required headers, environment variables, permissions and provider costs before setup.

Read the remote connection details

URL and transport

Open a listing’s connection details to inspect its remotes. Streamable HTTP is the preferred registry transport; SSE is a legacy option. Use a transport your client supports. A listing may also include a local package.

Template variables

A URL containing a placeholder such as {tenant_id} needs the provider’s value before setup. Review any declared variables, choices, defaults and secret flags. The published template is not a ready-to-use URL.

Headers and authentication

Review declared headers, required values and secret flags. Missing headers do not prove anonymous access: the provider may require OAuth or other setup. ToolCargo keys authenticate its own hosted connectors, not third-party servers.

These are publisher declarations, not availability, security or client-compatibility checks by ToolCargo. Confirm permissions and pricing with the provider. See the official remote-server metadata reference.

This is a dated index of publisher-provided listings, not the complete registry or a ToolCargo verification. Third-party servers run with their own providers, credentials and pricing. ToolCargo discovery supplies setup metadata; it does not run their tools. Explore ToolCargo's hosted connectors.
