query

MCP tool from Signal MCP Spec by aiassistsecure

How to use it

query is exposed by the Signal MCP Spec MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the query tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.

intent_filter

uses the same enum as the resource (signal://lexicon), so an agent that's read the lexicon knows exactly what to pass.

scope

groups spatial/temporal filters so the flat namespace stays readable.

sources

is optional — the server picks intelligently by default. This is progressive disclosure: easy path is one parameter (query), power path is five.
