The primary manifest — the file an agent reads to learn what this artifact does.
An MCP (Model Context Protocol) server for interacting with James Bloom's MockServer. This enables AI assistants to create mock HTTP expectations, verify requests, clear state, and manage MockServer instances programmatically.
You need a running MockServer instance:
# Using Docker (easiest)
docker run -d -p 1080:1080 mockserver/mockservernpx mockserver-mcpnpm install -g mockserver-mcp
mockserver-mcp| Variable | Description | Default |
|---|---|---|
MOCKSERVER_HOST | MockServer hostname | localhost |
MOCKSERVER_PORT | MockServer port | 1080 |
Add to your MCP client configuration file (e.g., Claude Desktop, Kiro, Cursor):
{
"mcpServers": {
"mockserver": {
"command": "npx",
"args": ["-y", "mockserver-mcp"],
"env": {
"MOCKSERVER_HOST": "localhost",
"MOCKSERVER_PORT": "1080"
}
}
}
}For shared team MockServer, change MOCKSERVER_HOST to your server's address.
Create a mock HTTP expectation on MockServer.
Parameters:
httpRequest (required): Request matching criteriamethod: HTTP method (GET, POST, PUT, DELETE, etc.)path: URL path to matchqueryStringParameters: Query parameters to matchheaders: Headers to matchbody: Body matcher with type (STRING, JSON, REGEX, XPATH, JSON_PATH) and valuehttpResponse: Response configurationstatusCode: HTTP status codeheaders: Response headersbody: Response body (string or object)delay: Response delay with timeUnit and valuetimes: How many times to match (remainingTimes, unlimited)timeToLive: Expectation lifetime (timeUnit, timeToLive)Example:
{
"httpRequest": {
"method": "GET",
"path": "/api/users"
},
"httpResponse": {
"statusCode": 200,
"body": { "users": [] }
}
}Verify that requests matching criteria were received by MockServer.
Parameters:
httpRequest (required): Request matching criteria (same as create_expectation)times: Expected request countatLeast: Minimum number of requestsatMost: Maximum number of requestsexactly: Exact number of requestsExample:
{
"httpRequest": {
"method": "POST",
"path": "/api/orders"
},
"times": {
"atLeast": 1
}
}Clear expectations and recorded requests from MockServer.
Parameters:
httpRequest (optional): Request matcher to clear specific expectations. If not provided, clears all.Example:
{
"httpRequest": {
"path": "/api/users"
}
}Perform a full reset of MockServer, clearing all expectations and recorded requests.
Parameters: None
Retrieve recorded requests from MockServer.
Parameters:
httpRequest (optional): Request matcher to filter recorded requestsExample:
{
"httpRequest": {
"method": "GET"
}
}Get MockServer connection status and configuration.
Parameters: None
API mocking enables early testing — start building and testing your frontend or integrations before the backend is ready. No more waiting. Ship faster.
