feat: Add MCP (Model Context Protocol) support for Feast feature server #5406

YassinNouh21 · 2025-05-31T10:45:20Z

What this PR does / why we need it:

This PR implements Model Context Protocol (MCP) support for Feast's feature server, enabling AI agents and applications to interact with Feast feature stores through standardized MCP interfaces.

Key Features:

Optional MCP Integration: MCP support is disabled by default and can be enabled via feature store YAML configuration
New Feature Server Type: Introduces mcp feature server type with configurable options
MCP Tools: Exposes Feast functionality through MCP tools:
- get_online_features: Retrieve feature values for entities
- list_feature_views: List all available feature views
- list_feature_services: List all available feature services
- get_feature_store_info: Get feature store metadata
MCP Resources: Provides JSON resources for feature views and services
Comprehensive Testing: Includes unit tests for all MCP functionality
Documentation & Examples: Complete example configuration and usage guide

Implementation Details:

Uses fastapi_mcp library for MCP protocol integration
Graceful fallback when MCP dependencies are not installed
Proper error handling and logging throughout
Type-safe implementation with full mypy compliance
Follows Feast's existing patterns for feature server extensibility

Which issue(s) this PR fixes:

Fixes #5404

Thank you for this!

I'd also add this to the GenAI docs and make it an extra that we enable with pip install feast[mcp]

@franciscojavierarceo done can u check it

Does this mean you can't run MCP locally?

Yes, MCP can absolutely run locally.
The confusion arises from seeing "local" and "mcp" as separate configuration types in the code. However, these represent different feature server capabilities, not deployment locations:

type: local = Basic feature server without MCP protocol support

type: mcp = Feature server with MCP protocol support (can still run on localhost)

YassinNouh21 · 2025-05-31T17:27:09Z

@franciscojavierarceo can u take a look again

redhatHameed · 2025-05-31T17:50:17Z

examples/mcp_feature_store/feature_store.yaml

+    feature_logging:
+        enabled: false
+
+entity_key_serialization_version: 3


as mcp will only implement onlinstore, instead of make new section with feature_server is that possible we can add into into onlinstore section WDYT ?

online_store: type: sqlite path: data/online_store.db mcp: enabled: true server_name: "feast-feature-store" server_version: "1.0.0" feature_logging: enabled: false```

While embedding MCP config in the online_store section might seem logical, I'd recommend using a separate feature_server section instead:

online_store: type: sqlite path: data/online_store.db feature_server: type: mcp enabled: true mcp_enabled: true mcp_server_name: "feast-feature-store" mcp_server_version: "1.0.0" feature_logging: enabled: false

Why this approach is better:

MCP is a feature server protocol for API exposure, not an online store storage concern

Follows the same pattern as other feature server types (local, etc.)

The McpFeatureServerConfig class inherits from BaseFeatureServerConfig, indicating it's designed as a feature server component

What do u think @franciscojavierarceo @ntkathole

I'm good with it.

What is the purpose of these 3 fields

type: mcp enabled: true mcp_enabled: true

my suggestion was if we change the name for example mcp_server then maybe we don't required these field. you can look mcp_server section if user added that section then it will be enabled else by default it will disabled/null. Let me know if that make sense or the current approach is more better. Thanks

What @redhatHameed suggested 👍

In short MCP online store config looks like:

feature_server: type: mcp mcp_server_name: "feast-feature-store" mcp_server_version: "1.0.0" feature_logging: enabled: false

No hassle of enabling explicitely.

even if we can make like, that will remove extra type field.

mcp_server: mcp_server_name: "feast-feature-store" mcp_server_version: "1.0.0" feature_logging: enabled: false

@redhatHameed mind addressing in a follow up PR? I think this is good enough as an MVP

I don't see the mcp logic in the PR? Or that's up to the user to implement?

franciscojavierarceo · 2025-06-01T00:15:43Z

It comes from the MCP fast api library addition and config I believe.

@YassinNouh21 can you add a unit test to test the MCP server works in the feature server?

can you add a unit test to test the MCP server works in the feature server?

Actually I tested those. I don't understand what do u mean?

What the tests cover:
Already tested:

MCP configuration validation
MCP server initialization with FastAPI app
Error handling when MCP is not available
Integration with the _add_mcp_support_if_enabled function from feast.feature_server

What might be missing:
Not fully tested:

Full end-to-end test of the feature server with MCP enabled
Testing the actual MCP endpoints/functionality

Do you see any traceback here? Initially milvus-lite does take long time to build, tried keep it running for few mins?
