Langflow
Connect a Langflow agent to Pushary with the MCP Tools component, so it can send you updates and ask you questions you answer on your phone.
Langflow agents can use Pushary through Langflow's MCP Tools component. MCP (Model Context Protocol) is the standard way AI apps call outside tools. You store your Pushary key as a Langflow credential, add Pushary as an MCP server, and connect it to an Agent. The agent can then send you updates and ask you questions on your phone.
This is the server URL you enter in Langflow:
https://pushary.com/api/mcp/mcpThe agent chooses when to call a tool. This connection does not hold a separate action in a flow until you approve it.
Connect Pushary
You need a Pushary account with a connected phone and an API key from Settings > API keys. Use the key for the account that owns your phone. Do not put the key in a flow, a prompt or the server URL.
Store your key as a credential
In Langflow, open Settings > Global Variables > Add New. Name the variable PUSHARY_BEARER and choose Credential. Set its value to Bearer followed by your key, then save:
Bearer pk_xxx.xxxAdd the MCP server
Open Settings > MCP Servers > Add MCP Server and choose Streamable HTTP/SSE. Name the server pushary and set the URL to https://pushary.com/api/mcp/mcp.
Add the header
Under Headers, set the key to Authorization and select PUSHARY_BEARER as its value. Save the server. Langflow lists the Pushary tools.
Build the flow
In a flow, add Chat Input, Agent and Chat Output. Choose a model provider for the Agent.
Give the Agent the Pushary tools
Drag pushary from the MCP sidebar onto the canvas. Turn on Tool Mode on the MCP Tools component, and connect its Toolset output to the Agent's Tools input.
Tell the Agent when to ask
In the Agent's instructions, say when to use ask_user and send_notification. For a yes/no question, use ask_user with type: "confirm" and wait for the answer. Treat no answer, a decline or an expired question as no approval.
Test it in the Playground
Ask the agent to send a harmless test notification. Then ask it to send a yes/no question through ask_user, and answer it on your phone. The answer shows in Langflow.
An Agent instruction guides the agent and enforces nothing. If an approval must protect a deployment, a payment or another business action, bind the exact action and recipient in your application, and verify the Pushary decision before you run that action. Partner workflows that address customers use the Partner server API and customer IDs instead of this personal MCP connection.
Why does the test fail?
- The result shows
sent: 0or ano_recipientsstatus. No phone is connected. Connect one in Pushary under Settings > Connections. - Langflow lists the tools, but a call returns
401 Unauthorized. Check thatPUSHARY_BEARERholds your current key with theBearerprefix. Langflow can list the tools without a valid key, so a tool list alone does not prove the key works.
See Langflow's MCP client guide for its current editor controls.
