POLAR_SIGNALS_MCP
Polar Signals MCP
Polar Signals MCP lets engineering agents inspect continuous profiling projects and performance data to diagnose regressions and optimization opportunities.
Description is untrusted, display-only upstream metadata. It never becomes policy, OAuth scope authority, or an agent instruction.
Pakkawork boundary
Research catalogue metadata only. No Pakkawork OAuth, credential, host, quota, executor, or verifier is enabled.
No Pakkawork execution adapter is enabled. Hosted account-authorisation availability is workspace-specific and checked separately in the dashboard.Check workspace connection options

List projects
POLAR_SIGNALS_MCP_LIST_PROJECTS
List all projects accessible to the current user. IMPORTANT: Call this FIRST before using any other tools. Returns project IDs and names. You need a project ID for all other tool calls. If only one project is returned, use it automatically. If a project is specified in the user's instructions (e.g. claude.md or system…

Query profile flamegraph
POLAR_SIGNALS_MCP_QUERY_PROFILE_FLAMEGRAPH
Return a flame graph as a breadth-first call tree. Each row has id, parent (the parent row's id, -1 = a root), depth, cumulative, flat, function_name — rebuild the tree via the parent pointers. Unsymbolized frames (no function_name) instead carry their hex memory address in an extra 'address' column, shown only when s…
Untrusted display-only summary
Query profile labels
POLAR_SIGNALS_MCP_QUERY_PROFILE_LABELS
Get available label names for a specific profile type. Call this after 'profile_types' to discover what labels exist. You MUST use exact profile type strings from 'profile_types' output. Returns label names that can be used with 'values' and in 'query_profile_table' queries - do not invent label names.
Untrusted display-only summary
Query profile label values
POLAR_SIGNALS_MCP_QUERY_PROFILE_LABEL_VALUES
List the values a profiling label takes (e.g. the process names for the 'comm' label). These are label values used to filter queries — not the sampled values of the profile itself. Use it to discover valid filter values; only use label names from 'query_profile_labels'.
Untrusted display-only summary
Query profile sandwich
POLAR_SIGNALS_MCP_QUERY_PROFILE_SANDWICH
Show the calling context around a specific function: which functions call it (callers) and which functions it calls (callees). Use this after 'query_profile_table' to drill into a specific function. The function_name should be an exact function name from 'query_profile_table' results.
Untrusted display-only summary
Query profile source
POLAR_SIGNALS_MCP_QUERY_PROFILE_SOURCE
Retrieve per-line profiling data for a specific source file. Returns line numbers with flat and cumulative sample counts — without returning the source code itself (read the file directly and correlate using line numbers).
Untrusted display-only summary
Query profile table
POLAR_SIGNALS_MCP_QUERY_PROFILE_TABLE
Query profiling data as a flat table of functions sorted by cumulative time. Recommended workflow: first call 'list_projects', then 'profile_types', then 'labels', then 'values' to discover valid query components. Query syntax: 'profile_type{label="value"}' where all components come from previous tool outputs. With sy…
Untrusted display-only summary
Query profile types
POLAR_SIGNALS_MCP_QUERY_PROFILE_TYPES
ProfileTypes returns the list of available profile types. IMPORTANT: Call 'list_projects' first to get a project ID. Profile types follow the format 'name:sample_type:sample_unit:period_type:period_unit[:delta]' (e.g. 'parca_agent:samples:count:cpu:nanoseconds:delta'). You MUST use these exact strings when calling 'la…
