SkyWalking-MCP: A Model Context Protocol (MCP) server for integrating AI agents with Skywalking OAP and the surrounding ecosystem.
SkyWalking: an APM(application performance monitor) system, especially designed for microservices, cloud native and container-based (Docker, Kubernetes, Mesos) architectures.
# Clone the repository git clone https://github.com/apache/skywalking-mcp.git cd skywalking-mcp && go mod tidy # Build the project make
Usage: swmcp [command] Available Commands: completion Generate the autocompletion script for the specified shell help Help about any command sse Start SSE server stdio Start stdio server streamable Start Streamable server Flags: -h, --help help for swmcp --log-command When true, log commands to the log file --log-file string Path to log file --log-level string Logging level (debug, info, warn, error) (default "info") --read-only Restrict the server to read-only operations --sw-url string Specify the OAP URL to connect to (e.g. http://localhost:12800) -v, --version version for swmcp Use "swmcp [command] --help" for more information about a command.
You could start the MCP server with the following command:
# use stdio server bin/swmcp stdio --sw-url http://localhost:12800 # or use SSE server bin/swmcp sse --sse-address localhost:8000 --base-path /mcp --sw-url http://localhost:12800
{ "mcpServers": { "skywalking": { "command": "swmcp stdio", "args": [ "--sw-url", "http://localhost:12800" ] } } }
If using Docker:
make build-image to build the Docker image, then configure the MCP server like this:
{ "mcpServers": { "skywalking": { "command": "docker", "args": [ "run", "--rm", "-i", "-e", "SW_URL", "skywalking-mcp:latest" ], "env": { "SW_URL": "http://localhost:12800" } } } }
SkyWalking MCP provides the following tools to query and analyze SkyWalking OAP data:
| Category | Tool Name | Description | Key Features |
|---|---|---|---|
| Trace | get_trace_details | Get detailed trace information | Retrieve trace by ID; Multiple views: full (complete trace), summary (overview with metrics), errors_only (error spans only); Detailed span analysis |
| Trace | get_cold_trace_details | Get trace details from cold storage | Query historical traces from BanyanDB; Multiple views: full, summary, errors_only; Duration-based search; Historical incident investigation |
| Trace | query_traces | Query traces with intelligent analysis | Multi-condition filtering (service, endpoint, duration, state, tags); Multiple views: full (raw data), summary (intelligent analysis with performance insights), errors_only (error traces); Sort options; Slow trace detection; Performance metrics and statistics |
| Metrics | query_single_metrics | Query single metric values | Get specific metric values (CPM, response time, SLA, Apdex); Multiple entity scopes (Service, ServiceInstance, Endpoint, Process, Relations); Time range and cold storage support |
| Metrics | query_top_n_metrics | Query top N metric rankings | Rank entities by metric values; Configurable top N count; Ascending/descending order; Scope-based filtering; Performance analysis and issue identification |
| Log | query_logs | Query logs from SkyWalking OAP | Filter by service, instance, endpoint, trace ID, tags; Time range queries; Cold storage support; Pagination support |
| MQE | execute_mqe_expression | Execute MQE expressions for metrics | Execute complex MQE (Metrics Query Expression) queries; Support calculations, aggregations, comparisons, TopN, trend analysis; Multiple result types (single value, time series, sorted list); Entity filtering and relation metrics; Debug and tracing capabilities |
| MQE | list_mqe_metrics | List available metrics for MQE | Discover available metrics for MQE queries; Filter by regex patterns; Get metric metadata (type, catalog); Support service, instance, endpoint, relation, database, and infrastructure metrics |
| MQE | get_mqe_metric_type | Get metric type information | Get detailed type information for specific metrics; Understand metric structure (regular value, labeled value, sampled record); Help with correct MQE expression syntax |
