Overview

MCP Canary is a remote MCP server at https://api.mcpcanary.com/mcp for examining other MCP endpoints and retrieving MCP Canary plan information. Its inspect_endpoint tool reports a target server's transport, protocol version, available tools, and side-effect hints without invoking those tools. get_pricing returns MCP Canary plans. Both tools are read-only and can be used anonymously, making the service useful for checking an MCP endpoint before connecting an agent to it.

Use cases

  • Inspect a remote MCP server before adding it to an agent
  • Review an endpoint's available tools and protocol version
  • Check transport details without invoking target tools
  • Retrieve MCP Canary plan and pricing information

Key features

  • Remote streamable MCP endpoint
  • MCP server inspection
  • Tool and protocol metadata reporting
  • Side-effect hint reporting
  • Anonymous read-only operations
  • Plan and pricing lookup

How MCP Canary works

What MCP Canary does

MCP Canary provides two read-only MCP tools through a remote endpoint. The primary inspection tool examines another remote MCP server and reports how it communicates, which MCP protocol version it uses, what tools it exposes, and whether those tools carry side-effect hints. Inspection is metadata-oriented: it does not call a tool on the target server.

The second tool returns MCP Canary plan and pricing information. Together, the tools suit developers who need to assess an MCP endpoint or retrieve service plan details from an MCP-compatible client.

How it works

Connect an MCP client to the streamable remote endpoint at https://api.mcpcanary.com/mcp. After the connection is available, invoke inspect_endpoint with a remote MCP server to receive its transport, protocol version, tool inventory, and side-effect hints. The inspection step is separate from tool execution, so the target server's tools are not called as part of the check.

get_pricing queries MCP Canary for its available plans. Requests to both tools are anonymous, and both operations are read-only.

Setup and configuration

Use the MCP endpoint below when configuring a client that supports remote MCP connections:

https://api.mcpcanary.com/mcp

The service does not require an API key or other authentication variable for these anonymous tools. The official registry name is com.mcpcanary/inspect.

Tools and capabilities

  • inspect_endpoint: Inspects a remote MCP server without calling any of its tools. Reports the server's transport, MCP protocol version, exposed tools, and side-effect hints.
  • get_pricing: Returns MCP Canary plan and pricing information.

The inspection result is useful for confirming the shape of an MCP endpoint before deciding whether to add it to an agent configuration. Side-effect hints can help distinguish tools that may alter state from those intended for observation, while the no-call behavior keeps the inspection focused on server metadata.

Limitations and notes

MCP Canary reports information about a target endpoint; it does not execute the target server's tools through inspect_endpoint. The available operations are limited to endpoint inspection and MCP Canary pricing. Both operations are read-only and anonymous. Access requires an MCP client capable of connecting to the remote endpoint rather than a local-only server configuration.

Frequently Asked Questions about MCP Canary

MCP Canary is an MCP server that connects to remote MCP endpoints for inspection and provides MCP Canary plan details. Its main tools are inspect_endpoint, which reports transport, protocol version, tools, and side-effect hints without calling a target tool, and get_pricing, which returns available plans.

Connect an MCP client to https://api.mcpcanary.com/mcp. The endpoint provides the inspect_endpoint and get_pricing tools through a remote MCP connection, and both tools can be used anonymously.

Yes, inspect_endpoint examines a remote MCP server without calling any of its tools. It reports the target's transport, protocol version, available tools, and side-effect hints.

No, MCP Canary's two tools are anonymous and read-only. Connect to the remote MCP endpoint and use inspect_endpoint or get_pricing without supplying authentication credentials.
