MCP Tools
The SigParser MCP server exposes 21 tools through a standardized interface. All query tools support structured JSON filters with AND/OR grouping, sorting, pagination, and field selection.
Tip: AI agents should call get_sigparser_skill first. It returns a built-in guide that teaches the agent how to use SigParser's tools most effectively for relationship intelligence tasks.

The MCP server includes 6 pre-built prompt templates that guide AI agents through multi-step relationship intelligence tasks. These prompts are designed to coordinate multiple tools into a single, structured workflow.
Prompt | Description |

sigparser://fields/companies) — Returns all available company field definitions with the same level of detail.
