254 | poetry run python splunk_mcp.py stdio
255 | ```
256 |
257 | ### Docker Usage
258 |
259 | The project supports both the new `docker compose` (V2) and legacy `docker-compose` (V1) commands. The examples below use V2 syntax, but both are supported.
260 |
261 | 1. SSE Mode (Default):
262 | ```bash
263 | docker compose up -d mcp
264 | ```
265 |
266 | 2. API Mode:
267 | ```bash
268 | docker compose run --rm mcp python splunk_mcp.py api
269 | ```
270 |
271 | 3. STDIO Mode:
272 | ```bash
273 | docker compose run -i --rm mcp python splunk_mcp.py stdio
274 | ```
275 |
276 | ### Testing with Docker
277 |
278 | The project includes a dedicated test environment in Docker:
279 |
280 | 1. Run all tests:
281 | ```bash
282 | ./run_tests.sh --docker
283 | ```
284 |
285 | 2. Run specific test components:
286 | ```bash
287 | # Run only the MCP server
288 | docker compose up -d mcp
289 |
290 | # Run only the test container
291 | docker compose up test
292 |
293 | # Run both with test results
294 | docker compose up --abort-on-container-exit
295 | ```
296 |
297 | Test results will be available in the `./test-results` directory.
298 |
299 | ### Docker Development Tips
300 |
301 | 1. **Building Images**:
302 | ```bash
303 | # Build both images
304 | docker compose build
305 |
306 | # Build specific service
307 | docker compose build mcp
308 | docker compose build test
309 | ```
310 |
311 | 2. **Viewing Logs**:
312 | ```bash
313 | # View all logs
314 | docker compose logs
315 |
316 | # Follow specific service logs
317 | docker compose logs -f mcp
318 | ```
319 |
320 | 3. **Debugging**:
321 | ```bash
322 | # Run with debug mode
323 | DEBUG=true docker compose up mcp
324 |
325 | # Access container shell
326 | docker compose exec mcp /bin/bash
327 | ```
328 |
329 | Note: If you're using Docker Compose V1, replace `docker compose` with `docker-compose` in the above commands.
330 |
331 | ### Security Notes
332 |
333 | 1. **Environment Variables**:
334 | - Never commit `.env` files
335 | - Use `.env.example` as a template
336 | - Consider using Docker secrets for production
337 |
338 | 2. **SSL Verification**:
339 | - `VERIFY_SSL=true` recommended for production
340 | - Can be disabled for development/testing
341 | - Configure through environment variables
342 |
343 | 3. **Port Exposure**:
344 | - Only expose necessary ports
345 | - Use internal Docker network when possible
346 | - Consider network security in production
347 |
348 | ## Environment Variables
349 |
350 | Configure the following environment variables:
351 | - `SPLUNK_HOST`: Your Splunk host address
352 | - `SPLUNK_PORT`: Splunk management port (default: 8089)
353 | - `SPLUNK_USERNAME`: Your Splunk username
354 | - `SPLUNK_PASSWORD`: Your Splunk password
355 | - `SPLUNK_TOKEN`: (Optional) Splunk authentication token. If set, this will be used instead of username/password.
356 | - `SPLUNK_SCHEME`: Connection scheme (default: https)
357 | - `VERIFY_SSL`: Enable/disable SSL verification (default: true)
358 | - `FASTMCP_LOG_LEVEL`: Logging level (default: INFO)
359 | - `SERVER_MODE`: Server mode (sse, api, stdio) when using uvicorn
360 |
361 | ### SSL Configuration
362 |
363 | The tool provides flexible SSL verification options:
364 |
365 | 1. **Default (Secure) Mode**:
366 | ```env
367 | VERIFY_SSL=true
368 | ```
369 | - Full SSL certificate verification
370 | - Hostname verification enabled
371 | - Recommended for production environments
372 |
373 | 2. **Relaxed Mode**:
374 | ```env
375 | VERIFY_SSL=false
376 | ```
377 | - SSL certificate verification disabled
378 | - Hostname verification disabled
379 | - Useful for testing or self-signed certificates

1 | # Splunk MCP API Testing
2 |
3 | This directory contains scripts for testing the Splunk MCP API endpoints against a live Splunk instance.
4 |
5 | ## Overview
6 |
7 | The test suite includes:
8 |
9 | - `test_endpoints.py`: Main test script that tests all API endpoints against a running Splunk MCP server
10 | - `test_config.py`: Configuration settings for the test script
11 | - `run_tests.sh`: Shell script to run all tests and generate a report
12 |
13 | ## Testing Approaches
14 |
15 | This project has two different testing approaches, each with a different purpose:
16 |
17 | ### 1. Live Server Testing (this tool)
18 |
19 | This test script (`test_endpoints.py`) is designed to:
20 |
21 | - Test a **running instance** of the Splunk MCP server connected to a live Splunk deployment
22 | - Validate that all endpoints are working correctly in a real environment
23 | - Provide a quick way to check if the server is responding properly
24 | - Test both API mode and SSE (Server-Sent Events) mode
25 | - Generate reports about the health of the API
26 |
27 | Use this approach for:
28 | - Integration testing with a real Splunk instance
29 | - Verifying deployment in production or staging environments
30 | - Troubleshooting connectivity issues
31 | - Checking if all endpoints are accessible
32 |
33 | ### 2. Pytest Testing (in `/tests` directory)
34 |
35 | The pytest tests are designed to:
36 |
37 | - Unit test the code without requiring a real Splunk instance
38 | - Mock Splunk's responses to test error handling
39 | - Verify code coverage and edge cases
40 | - Run in CI/CD pipelines without external dependencies
41 | - Test internal code logic and functions
42 |
43 | Use this approach for:
44 | - Development and debugging
45 | - Verifying code changes don't break functionality
46 | - Ensuring proper error handling
47 | - Automated testing in CI/CD pipelines
48 |
49 | ## Requirements
50 |
51 | - Python 3.6+
52 | - Required packages: `requests`
53 |
54 | You can install the required packages using:
55 |
56 | ```bash
57 | pip install requests
58 | ```
59 |
60 | ## Configuration
61 |
62 | The `test_config.py` file contains default settings that can be overridden using environment variables:
63 |
64 | | Environment Variable | Description | Default Value |
65 | |----------------------------|----------------------------------|---------------------------|
66 | | `SPLUNK_MCP_API_URL` | Base URL for API mode | http://localhost:8000/api/v1 |
67 | | `SPLUNK_MCP_SSE_URL` | Base URL for SSE mode | http://localhost:8000/sse/v1 |
68 | | `SPLUNK_MCP_AUTO_DETECT` | Auto-detect server mode (true/false) | true |
69 | | `SPLUNK_MCP_CONNECTION_TIMEOUT` | Connection timeout in seconds | 5 |
70 | | `SPLUNK_MCP_TIMEOUT` | Request timeout in seconds | 30 |
71 | | `SPLUNK_MCP_VERBOSE` | Enable verbose output (true/false) | true |
72 | | `SPLUNK_MCP_TEST_QUERY` | Search query to test | index=_internal \| head 5 |
73 | | `SPLUNK_MCP_EARLIEST_TIME` | Earliest time for search | -1h |
74 | | `SPLUNK_MCP_LATEST_TIME` | Latest time for search | now |
75 | | `SPLUNK_MCP_MAX_RESULTS` | Max results for search | 5 |
76 | | `SPLUNK_MCP_TEST_INDEX` | Default index to use for tests | (empty) |
77 |
78 | ## Server Modes
79 |
80 | The Splunk MCP server can run in two different modes:
81 |
82 | 1. **API Mode**: Standard REST API endpoints (default)
83 | 2. **SSE Mode**: Server-Sent Events for streaming updates
84 |
85 | The test script can detect which mode the server is running in and adjust accordingly. You can also force a specific mode using the `--mode` command-line option.
86 |
87 | ## Running the Tests
88 |
89 | 1. Ensure the Splunk MCP API server is running and connected to a Splunk instance.
90 |
91 | 2. Run the test script:
92 |
93 | ```bash
94 | # Test all endpoints with automatic mode detection
95 | ./test_endpoints.py
96 |
97 | # List available endpoints
98 | ./test_endpoints.py --list
99 |
100 | # Test specific endpoints
101 | ./test_endpoints.py health list_indexes
102 |
103 | # Test in specific server mode
104 | ./test_endpoints.py --mode api
105 | ./test_endpoints.py --mode sse
106 |
107 | # Generate a full test report
108 | ./run_tests.sh
109 | ```
110 |
111 | ### Command-line Arguments
112 |
113 | The test script supports the following command-line arguments:
114 |
115 | - **Positional arguments**: Names of endpoints to test (if not specified, all suitable endpoints will be tested)
116 | - `--list`: List all available endpoints and exit
117 | - `--mode {api,sse}`: Force a specific server mode instead of auto-detecting
118 |
119 | ### Customizing Tests
120 |
121 | You can customize tests by setting environment variables:
122 |
123 | ```bash
124 | # Example: Test against a different server
125 | export SPLUNK_MCP_API_URL="http://my-splunk-server:8000/api/v1"
126 | export SPLUNK_MCP_SSE_URL="http://my-splunk-server:8000/sse/v1"
127 |
128 | # Example: Use a different search query
129 | export SPLUNK_MCP_TEST_QUERY="index=main | head 10"
130 |
131 | # Example: Set a specific index to test
132 | export SPLUNK_MCP_TEST_INDEX="main"
133 |
134 | # Run with customized settings
135 | ./test_endpoints.py
136 | ```
137 |
138 | ## Test Results
139 |
140 | The script will output results for each endpoint test and a summary at the end:
141 |
142 | - ✅ Successful tests
143 | - ❌ Failed tests with error details
144 |
145 | If any test fails, the script will exit with a non-zero status code, which is useful for CI/CD environments.
146 |
147 | When using `run_tests.sh`, a Markdown report file will be generated with details of all test results.
148 |
149 | ## Adding New Tests
150 |
151 | To add new tests, modify the `ALL_ENDPOINTS` dictionary in `test_endpoints.py`. Each endpoint should have:
152 |
153 | - `method`: HTTP method (GET, POST, etc.)
154 | - `path`: API endpoint path
155 | - `description`: Short description of the endpoint
156 | - `validation`: Function to validate the response
157 | - `available_in`: List of modes where this endpoint is available (`["api"]`, `["sse"]`, or `["api", "sse"]`)
158 | - `data`: (Optional) Request data for POST/PUT requests
159 | - `requires_parameters`: (Optional) Set to True if the endpoint requires parameters
160 |
161 | Example:
162 |
163 | ```python
164 | "new_endpoint": {
165 | "method": "GET",
166 | "path": "/new_endpoint",
167 | "description": "Example new endpoint",
168 | "validation": lambda data: assert_dict_keys(data, ["required_field1", "required_field2"]),
169 | "available_in": ["api", "sse"]
170 | }
171 | ```
```
