# MCP Explorer

The [MCP Explorer](https://developers.apideck.com/mcp-explorer) is a browser tool for the hosted Apideck MCP server at `https://mcp.apideck.dev/mcp`. It shows the exact JSON-RPC an agent sends in dynamic mode.

## What you can do

- Browse tools by domain with `list_tools`. The server lists at most 50 tools per call, so search narrows with `search_terms`.
- Read a tool's JSON Schema input contract with `describe_tool_input`.
- Run a tool with `execute_tool` against your own consumer and inspect the result.
- Deep link to one tool: `https://developers.apideck.com/mcp-explorer?tool=accounting-invoices-all`. API reference operations link here from their MCP tool name.

## Credentials and safety

Browsing and schemas need no credentials. Running a tool sends your `x-apideck-api-key`, `x-apideck-app-id` and `x-apideck-consumer-id` (and optionally `x-apideck-service-id`) directly from the browser to the MCP server; values stay in the browser tab's session storage.

Runs are read-only by default: the Explorer adds `?scopes=read`, so the server refuses write and destructive tools. Writes need an explicit opt-in, and destructive tools a second confirmation.
