Which integrations are available for this server?

Enables AI workflow orchestration using [Google](/mcp/servers/integrations/google)'s AI models for single prompts and multi-step workflows with context reduction. Enables AI workflow orchestration using [OpenAI](/mcp/servers/integrations/openai) models (e.g., gpt-4o) for single prompts and multi-step workflows with context reduction.

@relayplane/mcp-server

MCP server for efficient AI workflow orchestration with RelayPlane.

Why RelayPlane?

90%+ context reduction on multi-step pipelines.

When AI agents use MCP tools directly, they face two problems:

Tool definitions bloat context — 100k+ tokens for many tools
Intermediate results pass through context — a 50k token document copied between steps

RelayPlane workflows solve this by keeping intermediate results in the workflow engine, not your context window.

Available Tools

Tool	Purpose	Cost
`relay_run`	Test single prompt	Provider cost
`relay_workflow_run`	Test multi-step workflow	Provider cost
`relay_models_list`	List available models	Free
`relay_workflow_validate`	Validate DAG structure (no LLM calls)	Free
`relay_skills_list`	Discover pre-built skills	Free

Usage Example

// Single model call const result = await relay_run({ model: "openai:gpt-4o", prompt: "Summarize this document...", systemPrompt: "You are a helpful assistant." }); // Multi-step workflow const workflow = await relay_workflow_run({ name: "extract-and-validate", steps: [ { name: "extract", model: "openai:gpt-4o", prompt: "Extract all invoice fields from: {{input.document}}" }, { name: "validate", model: "anthropic:claude-3-5-sonnet-20241022", depends: ["extract"], prompt: "Validate the extracted data: {{steps.extract.output}}" } ], input: { document: "Invoice #123..." } }); console.log(workflow.contextReduction); // "94% (saved ~12k tokens)"

Budget Limits

Budget tracking protects you from runaway provider costs (OpenAI, Anthropic bills). RelayPlane is BYOK — we don't charge for API usage.

Default limits:

Daily: $5.00
Single call: $0.50
Calls per hour: 100

Override with CLI flags:

--max-daily-cost 10 --max-single-call-cost 1 --max-calls-per-hour 200

Pre-built Skills

Discover pre-built workflow patterns:

relay_skills_list({ category: "extraction" })

Available skills:

invoice-processor - Extract, validate, summarize invoices (97% context reduction)
content-pipeline - Research, draft, refine content (85% context reduction)
lead-enrichment - Enrich and score leads (90% context reduction)
document-qa - RAG-based document Q&A (75% context reduction)
code-review - Multi-stage code review (80% context reduction)
email-classifier - Classify and route emails (95% context reduction)
