Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

search_harnesses

Find an existing MCP server, SDK or agent framework that connects an AI agent to a service or does a task, from Loadbay's curated catalog. Use this before building an integration from scratch, or whenever the user asks for a tool, plugin, MCP server or harness for something (e.g. "MCP server for Postgres", "browser automation for agents", "crypto trading bot framework", "Slack integration"). Returns matches ranked by relevance then GitHub stars, each with repo URL, license, language, integrations and traits. All filters are optional; with none it returns the most-starred harnesses.

read-only

Argument	Type	Description
limit	integer	max results, default 10
query	string	what the agent needs to do or connect to, in plain words, e.g. "postgres", "stripe payments", "web scraping"
trait	string	require a trait: mcp = exposes an MCP server, oss = open source, keys = needs API keys, sandbox = runs sandboxed, guard = has guardrails
domain	string	restrict to one domain: trading (Trading), coding (Coding & DevOps), browser (Browser & computer), productivity (Productivity), data (Data & search), social (Social & comms), health (Health), science (Research & science), gaming (Gaming), media (Voice & media), robotics (Robotics)
integration	string	require a named integration, e.g. "GitHub", "Coinbase", "Slack" (case-insensitive)

repo*	string	public GitHub repo URL — must be open source (have a license)

domain*	string	domain key, one of: trading \| coding \| browser \| productivity \| data \| social \| health \| science \| gaming \| media \| robotics
traits	array	capability traits
summary*	string	what it connects to, what tools it exposes, how an agent uses it
language	string	primary language, e.g. TypeScript
integrations	array	what it connects to, e.g. ["Coinbase","Slack"]

support_loadbay

Only when the user asks to support or donate to Loadbay. Support the Loadbay builder with a USDC tip over x402. Returns the payable endpoint — GET it with your own x402 wallet to send the tip. Loadbay never holds funds; your wallet is the payer.

tip_harness

Only when the user asks to tip or pay a harness author. Tip in USDC over x402. Returns the payable endpoint and its payment details — GET it with an x402-capable client/wallet to actually send the tip (the agent's own wallet pays; Loadbay never holds funds).
