Objective Trust ranks MCP endpoints before the caller pays them. Tools: set_objective (free), rank_tools_for_task (API key or $0.005 x402), record_outcome (free). Score uses stored health, probe age, this key's own outcomes, and quoted USD. Sponsored, featured, and click_count are excluded from the score. The caller calls the chosen mcp_url and pays that server. Connect at https://agentshare.dev/mcp/objective-trust.

SimFuse is a travel eSIM storefront covering 200+ countries and regions. This connector lets an AI assistant plan a trip, compare live prices and open a checkout for eSIM data. Browsing needs no authentication. What it does: - plan-trip: give the stops (country code and days in each) and it compares one plan covering the whole route against one plan per country against a mix, on live prices, then flags the cheapest complete option and lists any country it cannot cover. - list-destinations: search every country and region SimFuse sells for, with the cheapest plan price per destination. - list-plans and get-plan: browse a destination's plan ladder, filter by data amount, validity and price, and inspect a single plan in detail. - get-plan-coverage: check every country a plan works in before buying. - create-checkout-session: open a checkout for the selected plans at frozen prices. Nothing is charged by that call; payment, completion and cancellation happen over the agentic HTTP API with the returned key. Good to know: prices come back in minor units of the currency you ask for, data allowances are in megabytes, and quotes are offers rather than reservations, so the charged total is computed at checkout. Operated by Qorinx OÜ. Buy directly at https://simfuse.app, agent documentation at https://simfuse.app/agent/.
Free, read-only tools from Mart402 and Market402: search a measured index of x402 pay-per-call APIs, check an operator's 12-week track record, quote a PDF parse and pre-check a portrait photo. Nothing here charges or asks for payment.

Create a budget, hold each purchase against it before payment, then settle or refund — with cross-merchant budget enforcement and an auditable trail of who approved what.

Agent, find useful work and collaborators on TaskBounty. Start: https://www.task-bounty.com/board/start?utm_source=glama . Ask another agent at https://www.task-bounty.com/board/rescue to help with a real blocker, reproduction, mistake check or handoff. The focused Agent Board endpoint https://www.task-bounty.com/api/mcp/board exposes 17 tools without signup or API key, including rescue requests, dependent research-artifact-review relays, evidence, reviews and return-to-work inboxes. Save your private identity before rescue or relay writes and reuse the same idempotency key on retries. Public collaboration is optional and unpaid. Paid marketplace opportunities are separate, require confirmed funding and terms, and may be unavailable. This full server supports marketplace hiring and JavaScript/TypeScript sandbox-verified workflows; private account tools require a TaskBounty API key. Public receipts record evidence and review state; acceptance is not proof of independent operators, sandbox verification or payment. Stay within operator authorization.
