Tool Reference

MCP tool names

The tables below list every tool the MCP server can expose, by its MCP tool name. MCP tool name is the name an agent calls and the name you pass to tools_to_register:

configure_mcp_server(
    mcp_server_instance=mcp,
    tools_to_register={"list_pipelines", "get_pipeline", "grep_object_store"},
)

Note

A few MCP tool names differ from the Python function that implements them (the function is what appears under Tool base functions below). Always register the MCP tool name listed in this table:

MCP tool name	Implemented by Python function
search_component_definitions	search_component_definition
get_from_object_store	create_get_from_object_store
get_slice_from_object_store	create_get_slice_from_object_store
grep_object_store	create_grep_object_store
sed_object_store	create_sed_object_store
yq_object_store	create_yq_object_store
search_docs	get_docs_search_tool

Pipelines

The Memory column describes how a tool interacts with the object store (see MCP server concepts):

• explorable: The tool's output is stored and returned as an @obj_id reference.
• referenceable: The tool accepts @obj_id references as parameters.
• none: The tool returns its output directly.

    pipeline_id: str | None = None,
    pipeline_version_id: str | None = None,
    dry_run: bool = False,
) -> PipelineDebugResult | str

Runs a pipeline configuration in debug mode: pin a breakpoint, resume a snapshot, or trace a full run.

Debugs a pipeline configuration directly (not a saved pipeline by name) -- pass the YAML you want to test, e.g. from get_pipeline_version, create_pipeline_version, or a local draft. The inline run trace is always returned, so a failure is visible even for a run that never reaches a breakpoint.

One call carries at most one of:

• break_at_component_name (with break_at_visit_count) -- run from inputs until the breakpoint is hit, then stop and return a resumable snapshot in the 'snapshot' field. Pass that back as resume_from to continue the run.
• resume_from -- replay a snapshot returned by a previous debug run to completion; inputs are ignored, they come from the snapshot.
• neither -- run the pipeline from inputs to completion as a plain debug run.

Parameters:

Name	Type	Description	Default
client	AsyncClientProtocol	The async client for API communication.	required
workspace	str	The workspace name.	required
yaml_configuration	str	The pipeline YAML configuration to debug.	required
inputs	dict[str, Any] | None	Named pipeline inputs keyed by the input name declared under the pipeline config's 'inputs' mapping (e.g. {"query": "What is love?"}). Ignored when resume_from is set.	None
break_at_component_name	str | None	Name of the component to break at. Mutually exclusive with resume_from; omit both to run to completion as a plain debug run.	None
break_at_visit_count	int	Break when the target has been visited this many times (0 breaks before the first visit; relevant for loops/cycles). Only used if break_at_component_name is set.	0
resume_from	dict[str, Any] | None	A snapshot returned by a previous debug run (its 'snapshot' field), replayed to completion. Mutually exclusive with break_at_component_name.	None
files	list[str] | None	File IDs to download and inject into the inputs declared under the pipeline config's 'inputs.files' mapping.	None
pipeline_id	str | None	Optional ID of the pipeline this debug run is associated with.	None
pipeline_version_id	str | None	Optional ID of the pipeline version to associate the run with (requires pipeline_id).	None
dry_run	bool	Best-effort stateless run: state-modifying components (e.g. DocumentWriter) are replaced with no-op equivalents so the pipeline can be inspected without side effects. Required for indexing pipelines (their document store carries no index until deploy time); harmless for query pipelines. Set it on resume too if the original run used dry_run, otherwise the run is rejected.	False

Returns:

Type	Description
PipelineDebugResult | str	PipelineDebugResult with status, result/snapshot, and the run trace, or an error message.

    pipeline_name: str,
    query_id: str,
) -> list[HaystackTraceLog] | str

Retrieves the log entries for a single Haystack pipeline run trace.

Returns the run's logs (e.g. to diagnose warnings or errors emitted during the run). Each entry includes the logger, level, message, timestamp, and extra fields.

Obtain query_id from list_pipeline_traces or list_pipeline_search_history.

If errors occur outside of the pipeline (e.g. in the API or search history service), they will not appear in the trace logs. Use the get_pipeline_logs tool to retrieve logs for the pipeline itself (e.g. startup errors, configuration issues, orother runtime problems).

Parameters:

Name	Type	Description	Default
client	AsyncClientProtocol	The async client for API communication.	required
workspace	str	The workspace name.	required
pipeline_name	str	Name of the pipeline.	required
query_id	str	UUID of the search history query.	required

Returns:

Type	Description
list[HaystackTraceLog] | str	List of log entries or an error message.

deepset_mcp.tools.get_pipeline_trace_span_tags async

Retrieves all tags for a single span within a Haystack pipeline run trace.

A span's tags carry the component-level detail, including its input and output (e.g. haystack.component.input / haystack.component.output) plus type and error information. Use this to inspect one component run in detail.

Obtain span_id from a span in a get_pipeline_trace response, and query_id from list_pipeline_traces or list_pipeline_search_history.

span_id	str	UUID of the span whose tags to retrieve.	required

Returns:

Type	Description
dict[str, Any] | str	The span's tag dictionary or an error message.

) -> PaginatedResponse[PipelineTraceSummary] | str

Lists Haystack pipeline run trace summaries for a specific pipeline.

Returns one lightweight summary per query run — query_id, query text, status, timing (duration_s, created_at), and failure details if the run failed. Summaries do not include spans or logs. Use this to browse runs, find slow or failed queries, then pass a query_id to get_pipeline_trace for the full execution trace (spans with essential tags such as component type), get_pipeline_trace_span_tags for a single span with full tags (including input/output), or get_pipeline_trace_logs for the logs of the trace.
