Measured tools (6)

• search_harnesses read-only

  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.

  Parameters:

  • 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)

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_harness read-only

  Get full details for one harness in the Loadbay catalog by slug (from search_harnesses): repo, license, stars, language, integrations, traits, summary and a shareable loadbay.xyz page. If the slug is unknown it returns the closest matches.

  Parameters:

  • slug (required) — string — the harness slug, e.g. browser-use

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_domains read-only

  List the domains (categories) in the Loadbay catalog with how many harnesses each holds. Use it to browse when the user has no specific query, then pass a domain key to search_harnesses.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• submit_harness

  List a new harness on Loadbay. The repo MUST be a public, open-source GitHub repository. Optionally include a USDC address to receive tips — it must also appear in the repo's loadbay.json, .github/FUNDING.yml or README.md (proof of ownership). The listing appears immediately, tagged as community-added (unverified).

  Parameters:

  • name (required) — string — harness name, e.g. my-coinbase-harness
  • repo (required) — string — public GitHub repo URL — must be open source (have a license)
  • domain (required) — string — domain key, one of: trading | coding | browser | productivity | data | social | health | science | gaming | media | robotics
  • summary (required) — string — what it connects to, what tools it exposes, how an agent uses it
  • author — string — your GitHub handle (defaults to the repo owner)
  • traits — array — capability traits
  • language — string — primary language, e.g. TypeScript
  • integrations — array — what it connects to, e.g. ["Coinbase","Slack"]
  • solanaAddress — string — Solana wallet (base58) to receive USDC (SPL) tips — optional, alongside or instead of Base
  • baseUsdcAddress — string — Base USDC wallet (0x…) to receive tips — must also appear in the repo's loadbay.json, .github/FUNDING.yml or README.md

  Hints: read-only no · destructive no · idempotent no · open-world yes

• tip_harness read-only

  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).

  Parameters:

  • slug (required) — string — the harness slug to tip
  • amount — number — tip amount in USD (default 1); the author receives USDC

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• support_loadbay read-only

  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.

  Parameters:

  • amount — number — tip amount in USD (default 5); the builder receives USDC

  Hints: read-only yes · destructive no · idempotent yes · open-world no
