Once connected (with or without auth), the tools, resources, and prompts command groups let you explore and exercise what the server exposes.

​
Tools

​
List tools

mcpjam tools list --url https://your-server.com/mcp --access-token $TOKEN
Returns every tool the server exposes, including names, descriptions, and input schemas.

​
Call a tool

mcpjam tools call --url https://your-server.com/mcp --access-token $TOKEN \
  --tool-name search_docs \
  --tool-args '{"query": "authentication"}'
Tool arguments are passed as a JSON string. The result includes the tool’s response content.
tools call supports --debug-out <path> to capture the full request/response trace for debugging. For stdio targets, the artifact records only the explicit env keys passed through -e/--env; inherited shell variables are not enumerated.
For a local stdio server: 
mcpjam tools list \
  --command npx \
  --args -y @modelcontextprotocol/server-everything \
  --cwd $PWD \
  -e DEBUG=1

​
Resources

​
List resources

mcpjam resources list --url https://your-server.com/mcp --access-token $TOKEN

​
Read a resource

mcpjam resources read --url https://your-server.com/mcp --access-token $TOKEN \
  --resource-uri "file:///docs/readme.md"

​
List resource templates

mcpjam resources templates --url https://your-server.com/mcp --access-token $TOKEN

​
Prompts

​
List prompts

mcpjam prompts list --url https://your-server.com/mcp --access-token $TOKEN

​
Get a prompt

mcpjam prompts get --url https://your-server.com/mcp --access-token $TOKEN \
  --prompt-name summarize \
  --prompt-args '{"text": "Hello world"}'

​
Common patterns

​
Enumerate the full server surface

# One-shot: doctor already sweeps everything
mcpjam server doctor --url https://your-server.com/mcp --access-token $TOKEN

# Or individually for focused output
mcpjam tools list --url $URL --access-token $TOKEN --format json | jq '.tools[].name'
mcpjam resources list --url $URL --access-token $TOKEN --format json | jq '.resources[].uri'
mcpjam prompts list --url $URL --access-token $TOKEN --format json | jq '.prompts[].name'

​
Test a specific tool end-to-end

# List to find the tool
mcpjam tools list --url $URL --access-token $TOKEN --format json \
  | jq '.tools[] | select(.name == "search_docs")'

# Call it
mcpjam tools call --url $URL --access-token $TOKEN \
  --tool-name search_docs \
  --tool-args '{"query": "setup guide"}' \
  --format json

​
No-auth servers

For servers that don’t require authentication (like mcp.excalidraw.com/mcp), simply omit the auth flags: 
mcpjam tools list --url https://mcp.excalidraw.com/mcp
mcpjam tools call --url https://mcp.excalidraw.com/mcp \
  --tool-name read_me
Stdio child processes inherit the parent shell environment by default. Use -e/--env to add values or override inherited ones for local subprocesses.
