About Doodle MCP Server
Connect your Doodle account to any AI agent and take full control of your group scheduling and meeting polls through natural conversation.
LangChain's ecosystem of 500+ components combines seamlessly with Doodle through native MCP adapters. Connect 10 tools via Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures. with LangSmith tracing giving full visibility into every tool call, latency, and token cost.
What you can do
- Poll Orchestration — List all Doodle polls and retrieve explicitly attached array vectors representing titles, states (OPEN/CLOSED), and final chosen options
- Live Poll Creation — Provision new group scheduling polls by commanding absolute explicit text payloads for specific dates and times
- Participant Auditing — Enumerate explicitly attached user responses active within any target poll to identify precisely who has voted
- Programmatic Voting — Trigger absolute response routing to add or remove participant votes, mapping literal preference arrays (Yes, No, If-need-be) exactly
- Collaboration Oversight — Retrieve and append string chats and contextual comments attached to specific poll IDs to verify participant feedback
- State Management — Change poll states to CLOSED to lock participation arrays and override core settings to dictate finally which exact option won
- Data Invalidation — Irreversibly vaporize explicit poll entities and wipe all associated votes and comments from the system permanently
The Doodle MCP Server exposes 10 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Doodle + LangChain Use Cases
Practical scenarios where LangChain combined with the Doodle MCP Server delivers measurable value.
RAG with live data: combine Doodle tool results with vector store retrievals for answers grounded in both real-time and historical data
Autonomous research agents: LangChain agents query Doodle, synthesize findings, and generate comprehensive research reports
Multi-tool orchestration: chain Doodle tools with web scrapers, databases, and calculators in a single agent run
Production monitoring: use LangSmith to trace every Doodle tool call, measure latency, and optimize your agent's performance
Doodle MCP Tools for LangChain (10)
These 10 tools become available when you connect Doodle to LangChain via MCP:
add_comment
Add a comment to a Doodle poll
add_participant
Provide a name and preference array (0=no, 1=yes, 2=if-need-be) matching option quantities. Add a participant vote to a Doodle poll programmatically
close_poll
Overrides the core settings dictating finally which exact option value string won. Close a Doodle poll and set the final chosen option
create_poll
Participants will be invited to vote on their preferred options. Create a new Doodle poll for group scheduling
delete_poll
Drops the raw data out of the system returning completely blank state. Permanently delete a Doodle poll and all associated participant votes and comments
get_comments
Retrieve all comments on a Doodle poll
get_poll
Retrieve detailed information for a specific Doodle poll by ID
list_participants
List all participants who voted on a Doodle poll
list_polls
Returns poll titles, states (OPEN/CLOSED), creation dates, number of participants, and chosen final options. List all Doodle polls created by the authenticated user
remove_participant
The core system inherently recalculates the total votes autonomously. Remove a participant and their votes from a Doodle poll
Example Prompts for Doodle in LangChain
Ready-to-use prompts you can give your LangChain agent to start working with Doodle immediately.
