A web-based, kanban-style, list-making application.
A web-based, kanban-style, list-making application. On Nagent, Trello is exposed as a fully-configurable project management integration that any agent can call — 329 actions, 5 triggers, and OAUTH1 authentication. No code is required to wire Trello into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Trello to automate the kinds of tasks project management teams previously handled manually. Concrete examples — each one is a single agent step in Nagent — include:
Trello also supports 4 event triggers ("Card Archived Trigger", "New Activity Trigger", "New Board Trigger", and more), which lets your Nagent agents react to Trello activity in real time — for example, kicking off a downstream workflow the moment a relevant event fires.
Every action and trigger is paired with a structured input/output schema (visible in the sections below), so when you wire Trello into Helix — our agentic agent builder — the editor knows exactly what each step expects and produces. Configure once, deploy anywhere across your Nagent agents.
Triggers are the entry points of agents built on Nagent — pick one to fire your agent the moment a Trello event happens. Webhook triggers run instantly; poll triggers check on an interval you configure. Each shows its configuration parameters and the payload your agent receives.

TRELLO_GET_SEARCHSearches Trello content (e.g., boards, cards, members) within specified organizations using a query and customizable result fields. IMPORTANT LIMITATIONS: - Search indexing has a delay: newly created/updated cards may not appear for several minutes. - For exact name matching or time-sensitive lookups, use TRELLO_GET_LISTS_CARDS_BY_ID_LIST or TRELLO_GET_BOARDS_CARDS_BY_ID_BOARD to enumerate cards directly, then filter by name. - The search uses word tokenization: queries like 'Payment failed when sending tips' are split into individual terms \['Payment', 'failed', 'when', 'sending', 'tips'\]. Common words may be ignored. - Set partial='true' (default) for better recall with prefix matching on the last search term.
Input parameters
The search query string. Trello tokenizes the query into individual words and searches for cards/boards/etc. containing those terms. Note: Common words like 'when', 'the', 'is' may be ignored as stop words.
A comma-separated list of card IDs to search for. Each card ID must be a 24-character hexadecimal string (e.g., '5f9f1b9b8f8f8f8f8f8f8f8f'). Do NOT use the short card ID from the card URL.
Enable partial/prefix matching for search terms ('true' or 'false'). Default is 'true'. When true, the last word in the query will match word prefixes (e.g., 'pay' matches 'payment'). When false, only exact word matches are returned. Setting to 'true' (recommended) improves search recall, especially for card names that may not be indexed immediately after creation.
A comma-separated list of board IDs to search within, or 'mine' to search all boards the user is a member of (default). Each board ID must be a 24-character hexadecimal string (e.g., '5f9f1b9b8f8f8f8f8f8f8f8f').

No publicly available marketplace agent is found using this tool yet. There are 58 agents privately built on Nagent that already use Trello.
Build on Nagent
Connect Trello to any Nagent agent in minutes — no API key management, no boilerplate. Just configure and deploy.
The five questions agent builders ask before adopting a new integration.
Open the External Integrations panel inside Nagent (app.nagent.ai/externalIntegration), find Trello, and click "Connect Now." You'll authenticate with OAUTH1 — Nagent handles credential storage and refresh automatically. Once connected, Trello is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Trello is connected, you configure its 329 actions and 5 triggers directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Trello steps into any workflow visually. Pick an action (e.g., one of those listed above), fill in the inputs (Helix knows the required vs. optional schema for each parameter), and connect it to upstream/downstream steps. Triggers run as the entry point of an agent, so when a Trello event fires, the agent kicks off automatically.
Every Trello action and trigger ships with a fully-typed schema — input parameters with name, type, required flag, and description, plus the output payload shape. The schemas are documented in the sections above. Helix uses these schemas to validate your configuration at build time and to type-check the data flowing between steps.
Yes. While Trello ships with 329 pre-built project management actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Trello together with other connected tools. For deeper customization, talk to our team about Nagent's Agentic AI Lab — forward-deployed engineers who build Trello-based workflows tailored to your business.
