Overview

AI-generated overview

Inspects a remote MCP endpoint's transport, protocol, tools and side-effect hints without calling any of its tools, and lists plan pricing.

What you can do
Inspect a remote MCP endpoint over Streamable HTTP or legacy SSE and list its tools, without calling them on the target. Classify each tool's side effects from its MCP hints. Report target problems as a failed status with a stable failure code such as TARGET_UNAVAILABLE or TARGET_AUTH_FAILED. Read MCP Canary plans, monthly prices in cents, limits and free trial details.
When to use it
Useful when you want to check what a remote MCP server exposes and how risky its tools look before connecting it to an assistant, or when you need its pricing and plan limits. It is a read-only inspection step, not a monitoring service.
Requirements
Remote Streamable HTTP endpoint; no authentication, environment variables or headers declared. Network access to the service and to the target endpoint being inspected.
Before you install
The instructions point to a separate CLI for scheduled monitoring; that is outside this endpoint and should be evaluated on its own. Inspecting an endpoint connects to a third-party target, so the target's address is shared with the service.

Installation

In SourceWeft

  1. Open MCP Canary in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.mcpcanary%2Finspect/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

MCP Canary plans, monthly prices (in cents), and limits, plus the free trial. The trial needs no payment and starts on the first monitor write.

Takes no parameters.

inspect_endpoint

Inspect MCP endpoint

Connects to a remote MCP endpoint (Streamable HTTP, then legacy SSE), lists its tools, and classifies each tool's side effects from its MCP hints. Never calls a tool on the target. A target problem is status=failed with a stable failure code (e.g. TARGET_UNAVAILABLE, TARGET_AUTH_FAILED, MCP_PROTOCOL_ERROR). Private and loopback addresses are rejected.

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
