Why it exists

Ask any AI assistant "write a Flyte V2 task with caching and 4 GPUs" and you get confidently wrong code: V1 imports, invented decorators, hallucinated resource kwargs. The assistant has no reliable channel into the Flyte ecosystem, so it fills the gap with training-data guesses.

flyte-mcp is that channel. It ships a versioned knowledge pack built directly from the flyte-sdk source tree and the Flyte Plugin Registry, plus a thin runtime bridge for executing tasks when a cluster is configured. The assistant stops guessing and starts answering.

What your assistant can do

All tools are pure Python, stdio transport, zero network calls unless you explicitly use the runtime bridge.

Example prompts that just work

• How do I cache a task and invalidate on input change?

• Show me a distributed PyTorch training example with A100s.

• Which Flyte plugin do I use for Snowflake, and what's the import?

• Migrate this flytekit V1 workflow to V2.

• What's the signature of TaskEnvironment?

Your assistant picks the right tools and assembles accurate answers.

Rebuilding the knowledge pack

Contributors and release automation can regenerate the pack from source:

python scripts/build_knowledge.py \
  --sdk-path /path/to/flyte-sdk \
  --registry /path/to/flyte-plugin-registry/src/data/plugins.json \
  --out src/flyte_mcp/data/flyte-v2-knowledge.json

Sources used:

• flyte-sdk/src/flyte/__init__.py — public symbols via AST

• flyte-sdk/examples/* — canonical patterns by theme

• flyte-sdk/README.md, FEATURES.md, CONTRIBUTING.md — meta docs

• flyte-plugin-registry — curated plugin catalog

flytesnacks is intentionally excluded: V2 consolidated examples in-tree.

Relationship to other Flyte MCP projects

• wherobots/flyte-mcp — runtime-only. Discovers and executes tasks on a deployed Flyte instance via API key. Complementary, not competing.

• unionai/claude-agents-public — Claude Code custom agents (system prompts, not an MCP server). Compose freely.

This project focuses on authoring: the moment a developer types a prompt asking about Flyte.

Roadmap

• GitHub Action to auto-rebuild the knowledge pack on every flyte-sdk release

• Listing in the official MCP Registry

• Local semantic search via small sentence-transformer model

• AST-based migration codemod (replacing the current regex pass)

• Log streaming tool (get_flyte_execution_logs) with tail support
