The Inspector supports URL query parameters for deep linking to a specific server or tab and for auto-connecting to a server on load.

​
Parameters

ParameterPurposeValues
serverSelect a connected server by ID, or open and connect to a server by URLConnection ID (URL) or HTTP(S) URL
autoConnectOpen Inspector and connect to a server automaticallyURL string or JSON config
tabOpen a specific tabtools, prompts, resources, chat, sampling, elicitation, notifications, playground
tunnelUrlTunnel subdomain or URL (preserved when navigating)URL string
embeddedRun Inspector in embedded mode (e.g. iframe)true
embeddedConfigEmbedded mode styling (background, padding)JSON string

​
server

Select an already-connected server by its connection ID (the server URL). If the value is an HTTP(S) URL and no matching connection exists, the Inspector treats it like autoConnect: it connects to that URL and then selects the server. Examples: 
# Select existing server by ID
/?server=https://mcp.example.com/mcp

# Open and connect to a new server (alias for autoConnect when not connected)
/?server=https://new-server.com/mcp

​
autoConnect

Open the Inspector and connect to a server automatically. Use a plain URL or a JSON object for advanced options (name, auth, transport type, etc.). Plain URL: 
/?autoConnect=https://mcp.example.com/mcp
JSON config (URL-encode the value in the query string): 
{"url":"https://mcp.example.com/mcp","name":"My Server","transportType":"sse"}
Supported JSON fields: url (required), name, transportType ("http" or "sse"), connectionType ("Direct" or "Via Proxy"), customHeaders, auth (OAuth tokens), requestTimeout, resetTimeoutOnProgress, maxTotalTimeout.
When passing a JSON object for autoConnect, URL-encode the value so special characters are valid in the query string.

​
tab

Open the Inspector with a specific tab selected. Valid values: tools, prompts, resources, chat, sampling, elicitation, notifications, playground Example: 
/?tab=tools
Combine with server or autoConnect to open a server and tab in one link: 
/?server=https://mcp.example.com/mcp&tab=tools

​
tunnelUrl

Used with the CLI tunnel; stores the tunnel subdomain or URL and is preserved when navigating. Typically set by the Inspector or CLI; you rarely need to set it manually.

​
embedded

Run the Inspector in embedded mode (e.g. inside an iframe with reduced chrome). Example: 
/?embedded=true

​
embeddedConfig

Optional JSON config for embedded mode styling. Use with embedded=true. Example (URL-encoded): 
{"backgroundColor":"#f5f5f5","padding":"16px"}

​
Example URLs

Open Inspector and auto-connect to a server: 
https://inspector.mcp-use.com/inspect?autoConnect=https://your-server.com/mcp
Open Inspector, connect to a server, and show the Tools tab: 
https://inspector.mcp-use.com/inspect?server=https://your-server.com/mcp&tab=tools
