MCP tools

Show chart MCP tool

Render a read-only inline chart as a standard `trend`, `comparison`, or `leaderboard` view from structured rows and series data.

Examples

Use charts when the user needs a compact visual for trends, comparisons, or ranked leaders. Use Show_Stats_Display for KPI cards instead.

Send teaming message

Send a chat message as the user in a teaming conversation: pass teaming_match_id for a match conversation or teaming_interest_id (prime side) for the team-hub conversation. The other party is notified by email and in-app, and before a match is accepted vendor identities may still be masked to them. Messages cannot be edited or deleted by the agent. REQUIRED: show the user the exact message text and obtain their explicit confirmation before calling; content must be the user-approved text verbatim.

Show document

Preview a GovTribe user file or government file in an interactive document viewer. Optionally enable document annotations so the user can mark up a WebViewer document and submit normalized annotation state back through Interaction_State without modifying the source file.
