What is union-mcp CLAUDE.md?

Project instructions for using Union MCP v2 to run heavy computation or data-processing work on a remote Flyte cluster. Flyte is a system for coordinating repeatable workloads across remote machines.

Use them for large parallel jobs, GPU work, large datasets, long-running calculations, model training, hyperparameter searches, and batch data processing.

They explain when a laptop may not have enough processing power, memory, graphics hardware, or runtime for the job.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.01841	$0.01841
Opus 5.5	$0.00736	$0.00736
Sonnet 5.5	$0.00368	$0.00368
Haiku 4.5	$0.00184	$0.00184

Security

Grade A, and why

union-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Union MCP v2

This file contains rules for using the Union MCP v2 server to run compute- or io-intensive workloads on a remote Flyte cluster.

When to Use Union MCP v2

Explicit Requests

If the user explicitly asks to run a workload on Flyte or Union, use the Union MCP v2 server.

Implicit Compute Needs

If a task requires compute resources beyond what a consumer laptop can handle, proactively suggest and use the Union MCP v2 server. This includes:

Large-scale parallel processing: Tasks that benefit from fan-out patterns (e.g., processing millions of items)
GPU workloads: Deep learning inference, embeddings, model training
Memory-intensive tasks: Processing large datasets that exceed typical RAM (8-16GB)
Long-running computations: Tasks that would take more than a few minutes on a laptop
Hyperparameter optimization: Parallel training runs across parameter combinations
Batch data processing: ETL jobs, data transformations on large datasets

Examples of When to Use Flyte

"Compute the sum of squares for 1 million numbers" → Fan-out to parallel workers
"Embed this 100k document dataset" → GPU batch inference
"Train models with different hyperparameters" → Parallel hyperparameter search
"Process this 50GB CSV file" → Distributed data processing
"Generate embeddings using a transformer model" → GPU acceleration

Examples of When NOT to Use Flyte

Simple calculations that complete in seconds
Reading/writing small files
Basic API calls
Local development tasks
Quick data exploration on small datasets

Workflow for Running Flyte Scripts

Follow these steps when running a workload on Flyte:

Step 1: Search for Examples

Before writing a script, search for relevant examples:

Search the local workspace for existing Flyte examples
Use search_flyte_sdk_examples for bleeding-edge SDK features
Use search_flyte_docs_examples for common use cases and patterns
Use search_full_docs for Flyte documentation and API reference

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
