wehub-resource-synccomposio-llamaindex
Adapts Composio tools to LlamaIndex's FunctionTool format so a LlamaIndex agent can call 1000+ apps through a single Composio session.
Installation
pip install composio composio-llamaindex llama-index llama-index-llms-openai
Set COMPOSIO_API_KEY (get one from dashboard.composio.dev/settings) and OPENAI_API_KEY in your environment:
export COMPOSIO_API_KEY=xxxxxxxxx
export OPENAI_API_KEY=xxxxxxxxx
Quickstart
Create a session for your user, fetch its tools, and hand them to a FunctionAgent. LlamaIndex drives the tool calls; each tool executes itself through Composio.
