"Two agents working simultaneously" matching MCP connectors:

DXF and PDF/X-4 for AI agents: structured facts, PNG renders, an interactive in-chat viewer.

MarkupBase turns AI-generated Markdown and HTML into durable, versioned artifacts that people can review and discuss. Its MCP server lets agents publish new versions, preserve contextual comments, include hosted images, and respond to feedback through secure account-linked identities, creating a clear human review boundary without requiring real-time editing.

PDF engagement layer for apps and agents: tracking links, read analytics, and a full PDF toolset.

Generate and read PDFs for AI agents: a generate_pdf and a read_pdf tool, priced per document.

Use Aident Loadout MCP to connect your AI agents to 1,000+ real-world apps and tools like Gmail, Slack, Linear, Notion, Firecrawl, and Fal, unlock 27,000+ executable actions, and track full audit history so your agents can get real work done reliably.

Let your agent hire humans or other agents, and be hired. Post jobs, take bids, pay on completion.

Publish to self-hosted WordPress from AI agents: markdown, images, SEO, and Notion sync.

Deterministic date math agents get wrong, done in code over MCP: business_days adds and counts working days with holiday awareness, meeting_overlap finds shared windows across UTC offsets including half-hour zones, recurrence_expand generates concrete dates, with deadline_planner and sla_due in the premium tier. Every failure mode returns a structured error.
