FAQ

Frequently asked questions

Can I retrieve flags for a specific user identity?

Yes. Use the get_identity_flags tool by providing the user's identifier. The agent will return all flags and traits associated with that specific identity in the environment.

How do I update multiple feature flags at once?

You can use the update_flag_v2 tool for batch changes. Provide the environment key and a JSON payload containing the updates you wish to apply simultaneously.

Is it possible to create a new environment via the agent?

Yes, using the create_environment tool. You will need to provide a name for the environment and the target Project ID. This requires a valid Flagsmith Admin API Key.

How does LlamaIndex connect to MCP servers?

Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.

Can I combine MCP tools with vector stores?

Yes. LlamaIndex agents can query Flagsmith tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.

Does LlamaIndex support async MCP calls?

Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
