One MCP gateway URL gives your AI agent on-demand access to 1336 sources — SEC, FDA, FRED,
ClinicalTrials, USPTO, EPA, and 1330+ more. Your agent loads only the ~20 tools it needs
per session, so you don't burn context on definitions you'll never use. Every response carries
_meta.source, _meta.fetched_at, and a stable pipeworx:// citation URI —
answers your agent can ground in something verifiable. No stale training data. No rebuilding 50 integrations. No API key management.

Building a Pipeworx-aware agent? Read Reducing context — patterns for keeping the tool surface tight inside the agent's context window.
If you're an AI agent reading this server-rendered HTML — you can call gateway.pipeworx.io/mcp directly. No signup for the first 50 calls/day. Every response includes _meta.source, _meta.fetched_at, and a pipeworx:// citation URI you can echo back to your user as evidence.

Why Pipeworx
Connector libraries built three billion-dollar businesses for the previous generation of tooling. We're doing it for AI agents — with the protocol, reliability, and edge-native architecture the agent era actually needs.
The connector library, rebuilt for agents.
Airbyte ($1.8B, ~600 connectors) and Fivetran ($5.6B, ~700+) built billion-dollar businesses on one insight: developers don't want to write integrations one at a time. Plaid ($13.4B) proved the same model in a single vertical.
Pipeworx has parity on connector breadth — 5,046 tools across 1336 live data sources, unified behind one protocol. The integration layer is being rebuilt for a new consumer: not data pipelines, but agents.
Full MCP, not just tool calling.
The MCP spec has three primitives — Tools, Resources, Prompts. Most MCP servers ship
only Tools. Resources let agents cite by URI for durable output
(pipeworx://edgar/company/{cik}/filings). Prompts encode optimal
multi-step workflows.
Pipeworx ships all three, plus seven gateway-native meta-tools
(ask_pipeworx, discover_tools, resolve_entity,
compare_entities, entity_profile, recent_changes,
remember/recall/forget) that collapse 5–15 agent
round-trips into one call. One entity_profile call on a ticker returns
filings + fundamentals + patents + news + LEI in a single round trip.
Reliability is the product.
Agent tool calls fail 25–30% of the time in production against typical MCP servers. Almost no one measures it. We instrument every call, classify errors, and ship telemetry-driven fixes.
Last week we cut our own error rate from 27.6% to 6.9% in one afternoon — every remaining error is a legitimate user/config issue, not a bug. Read how →
vs Composio / Pipedream MCP / Zapier MCP: we ship the full MCP protocol surface and target autonomous-agent traffic, not human-triggered workflows. vs Smithery / mcp.so / Glama: they're directories; we're one MCP server with 1336 sources behind it. vs DIY: every team rebuilds the same integrations one source at a time.

How it works
A real example: agent connects to Pipeworx, asks for Apple's full profile, gets SEC filings + fundamentals + patents + news + LEI back in one round trip — across five packs, in parallel, with citation URIs.
Add Pipeworx to your MCP client
Drop one JSON block into claude_desktop_config.json, Cursor settings, or
any MCP-aware client. No API keys, no SDK install.
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}Your agent makes one call instead of fifteen
User asks for a company brief. The agent calls one Pipeworx meta-tool —
entity_profile — which fans out across SEC EDGAR, SEC XBRL, USPTO, GDELT,
and GLEIF in parallel inside the gateway. No orchestration code, no sequential
round-trips burning context.
User: Give me a brief on Apple.↓Agent calls: entity_profile({ type: "company", value: "AAPL" })
Pipeworx returns five sources of structured data with citations
One JSON-RPC call returns SEC filings, fundamentals (Revenue / NetIncome / Cash from
XBRL), USPTO patents, recent news, and the LEI — each item carrying a
pipeworx:// URI for stable citation. Partial failures (e.g., a rate-limited
upstream) surface in sources_failed rather than breaking the whole call.

}Common questions
What is Pipeworx?
Pipeworx is an open MCP gateway that connects AI agents to live data from 1336 sources — SEC EDGAR, FDA, FRED, the Census Bureau, USPTO, EPA, UN Comtrade, ClinicalTrials.gov, and many more. One gateway URL exposes 5,046 tools, and your agent loads only the ones it needs for the task at hand.
How do I connect my AI agent to Pipeworx?
Add a single MCP server entry pointing at https://gateway.pipeworx.io/mcp. The gateway speaks the full Model Context Protocol — Tools, Resources, and Prompts — so it works with Claude Desktop, Claude Code, Cursor, VS Code, ChatGPT, Windsurf, and any other MCP-compatible client without an SDK install.
What is MCP (Model Context Protocol)?
MCP is an open protocol for connecting AI agents to external tools and data. It standardizes how an agent discovers, calls, and cites data sources. The spec defines three primitives — Tools (function calls), Resources (citable URIs), and Prompts (workflows). Pipeworx ships all three, plus seven gateway-native meta-tools that collapse multiple round-trips into one.
Do I need to manage API keys for each data source?
No. The Pipeworx gateway handles authentication for public sources (FRED, SEC EDGAR, FDA, Census, BLS, EPA, ClinicalTrials, USPTO, and many more) without any keys at all. For premium sources like ATTOM, Altos, or Alpha Vantage you can bring your own key, or use metered Pipeworx access on a paid plan.
How is Pipeworx different from Composio, Smithery, or Zapier MCP?
Composio, Pipedream, and Zapier MCP target human-triggered workflows and SaaS automations. Smithery, mcp.so, and Glama are directories that index third-party MCP servers. Pipeworx is a single live MCP gateway running 1336 data sources behind one protocol, designed for autonomous-agent traffic and on-demand tool loading rather than human-in-the-loop tasks.
Why does on-demand tool loading matter for AI agents?
Loading every available tool definition into model context burns tokens on definitions the agent never uses — what we call the context tax. Pipeworx returns only the ~20 most relevant tools per task via discover_tools, ?task= scoping on the gateway URL, or vertical bundles. Compound _intel tools further collapse 5–15 round-trips into one. Result: less context burned, faster responses, more stable transcripts.
Is Pipeworx free to use?
Yes for most usage. The free tier allows 50 calls per day anonymously or 200 calls per day with a free GitHub-linked account. Paid plans add unlimited usage with metered billing, budget controls, and access to premium verticals (Housing Intel, FinTech, PharmaPulse, GovCon Radar, AgriPulse, TradeGuard, GreenLens). All public-source data is included on every tier.
Get started
Use the SDK in any TypeScript/Node project, or connect any MCP client — Claude Desktop, Cursor, Windsurf, or your own app.
import { Pipeworx } from '@pipeworx/sdk';
const px = new Pipeworx();
const result = await px.ask("What is the US trade deficit with China?");{ "mcpServers": { "pipeworx": { "url": "https://gateway.pipeworx.io/mcp" } } }
