What is the Pumble MCP Server?

Connect your Pumble workspace to any AI agent and bring powerful automation directly to your team's communication hub.

What you can do

  • Read & Manage Channels — List all public and private channels, fetch detailed metadata, and dynamically create new discussion channels on the fly
  • Message Operations — Retrieve conversation histories, post new messages, update typos, or delete outdated announcements seamlessly
  • Interactive Reactions — Add emoji reactions to messages automatically to acknowledge requests without cluttering the chat
  • User Directory — List all workspace users and pull detailed profiles (including emails and time zones) to ensure accurate tagging

How it works

  1. Subscribe to this server
  2. Authorize via your Pumble API Key (generated in-app)
  3. Start managing your communications directly from Claude, Cursor, or any MCP-compatible client

Who is this for?

  • Engineering Teams — trigger automated status updates or bug reports directly into specific channels

Why CrewAI?

When paired with CrewAI, Pumble becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Pumble tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.

  • Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools

  • CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the mcps parameter and agents auto-discover every available tool at runtime

  • Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls

  • Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

FAQ

Frequently asked questions

01

How do I securely obtain my API Key?

Installation in Pumble is unique. In your workspace, click + Add apps in the left sidebar, find the API addon, and install it. After doing so, go to any chat input box in Pumble and type /api-keys generate. A private, ephemeral message will appear containing your secret token. Paste that token here.

02

Can my AI automatically reply to unread issues?

Yes. You can instruct your agent to regularly fetch messages from a specific channel (chat_history_messages). The agent can evaluate questions, generate answers based on your knowledge base, and then use chat_post_message to post the solution back to the team instantly.

03

Is it possible for the AI to react with emojis?

Absolutely. It uses the chat_add_reaction functionality. A common use case is having the agent process a batch of tickets reported in Pumble, and instruct it to leave a '✅' checkmark reaction on the original message to signify that work is complete.

04

What happens if a bot message has a typo?

Unlike standard webhooks, this integration provides full bidirectional control. If your AI posted something incorrect, simply ask it to update its previous message. It will fetch its message ID and push a new payload using the chat_update_message tool instantly without leaving double messages.

05

How does CrewAI discover and connect to MCP tools?

CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.

06

Can different agents in the same crew use different MCP servers?

Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.

07

What happens when an MCP tool call fails during a crew run?

CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.

08

Can CrewAI agents call multiple MCP tools in parallel?

CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.

09

Can I run CrewAI crews on a schedule (cron)?

Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.

10

MCP tools not discovered

Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.

11

Agent not using tools

Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".

12

Timeout errors

CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.

13

Rate limiting or 429 errors

Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
