LangChain integration for Cred. OAuth2 credential delegation for AI agents.

Install

pip install cred-langchain

Quick Start

import os
from cred_langchain import CredToolkit
from cred import ConsentRequiredError

toolkit = CredToolkit(
    agent_token=os.environ["CRED_AGENT_TOKEN"],
    user_id="user_123",
)
tools = toolkit.get_tools()
# tools = [CredDelegateTool, CredStatusTool, CredRevokeTool]

# Use with any LangChain agent
from langchain.agents import AgentExecutor
agent = AgentExecutor(agent=..., tools=tools)

Tools

Tool	Name	Description
CredDelegateTool	cred_delegate	Get an OAuth access token for a service
CredStatusTool	cred_status	List user's connected services
CredRevokeTool	cred_revoke	Revoke a service connection

Handling Consent

When a user hasn't connected a service yet, CredDelegateTool raises ConsentRequiredError. Catch it and redirect the user to e.consent_url to complete the OAuth flow.
