"A clean web agent named x402-cleanweb-agent" matching MCP servers:

Company profiles, site audits and page-to-JSON for AI agents.

An open source biomedical research agent that provides LLMs with 28 tools for drug discovery, protein analysis, literature search, medical imaging, omics, and sandbox execution, all running locally via Ollama and MedGemma.

Lets any MCP client call SWARM's live services — GitHub code-health scans, researched summaries and reports, and everyday utilities — paying per call in USDC on Base with no account or API key. Payments are metered by a spend cap and only settled after the work succeeds.

Enables AI agents to pay USDC per call for Asia market intelligence data via HTTP 402 protocol, no API keys or subscriptions required.

Enables local agent interactions with a mock Study of Us API through tools for health checks, catalogs, current user info, reports, and voting.

Enables users to discover, redact, and upload coding-agent traces, then earn USDC/USDT by selling access to those traces to researchers and model trainers.

Enables AI agents to run reproducible, high-recall literature search across seven source families with RRF fusion, fetch open-access full texts (falling back to abstracts), expand citations, export BibTeX/RIS, and audit reference coverage — all without any LLM API key, leaving query planning and writing to the agent. Multiple agent clients share one accumulating literature pool and background search jobs that keep running after sessions close.

Enables agent-native web search and multi-angle research synthesis with pay-per-call USDC payments on Base via x402, requiring no API keys or subscriptions.

A daily census of the AI agent tooling ecosystem on GitHub (MCP servers, agent frameworks, skills): look up whether a repository is still maintained and under what licence, search by words with status and licence filters, get the day's totals and two acted-on lists. Standard library only, public metadata only.

Enables querying verified AI agent news with citations and confidence scores. Provides tools for search, Q&A, article retrieval, and recommendations about AI agent tools, MCPs, and frameworks.

MCP server for Agent Reputation, enabling agent buyers to examine candidate agents' claims, outcomes, and independent sources, and to order evidence briefs before purchase.

Compound MCP agent that integrates EDINET, TDNET, e-Stat, and stock price sources for comprehensive Japanese company analysis, macro economic snapshots, and earnings monitoring through a single interface.

An autonomous MCP agent that helps you apply to fully funded MS and PhD programs by discovering professors, verifying faculty status, matching projects, and drafting cold emails.

Enables MCP clients to perform live web searches through Tavily and interact with a simple hello tool, suitable for research workflows and testing via the MCP Inspector.

An MCP server for Perplexity's Agent API, enabling multi-step web research with citations through tools to start, collect, and cancel research runs.

An MCP server that enables interaction with property-driven machine learning experiment pipelines, including listing experiments, retrieving configs, comparing runs, and executing experiments with approval gates and full tracing.

Enables AI assistants to research sponsorship contacts by searching and verifying professional emails through Monid, while saving missions, sources, and evidence locally.

Provides a suite of MCP tools for evidence-grounded investment research, including time-bounded search of reports and news, thesis verification against subsequent events, market response calculations, and generation of validated research briefs.

A browser research MCP server that emphasizes evidence-centric workflows, secure browser automation, and deterministic data extraction, with structured responses and artifact-based screenshots.

A paid callable research agent that provides source-backed reports, onchain intelligence, and claim verification via MCP tools for coding tools like Codex, Claude Code, Cursor, and Windsurf.

Provides email discovery, verification, enrichment, and company research through a remote MCP server.

Provides 11 composable MCP tools for A-share market research, covering quotes, news, technical signals, sector performance, portfolio risk, backtesting, and paper trading, with traceable data sources and calculation basis.

Enables MCP clients to fetch live football odds and team form, and flag matches where the market price diverges from a simple form-based estimate.

MCP server exposing 1,000+ pay-per-call API endpoints across agent infrastructure (memory, coordination, secrets, verification), data, compute, finance, weather, geography, and reference categories — payments via x402 protocol in USDC on Base.

Enables MCP-speaking AI research agents to coordinate plans, tasks, experiment runs, and claims on a shared evidence board, tracing each claim to the code that produced it and flagging results that need rechecking when dependencies change.

A local-first MCP server for tracking indoor horticulture metrics, enabling cold-stratification timelines, ericaceous soil pH validation, and transplant-shock recovery through a LangGraph agent with a local LLM.

MCP server that scans daily AI innovation sources (arXiv, Hacker News, GitHub) and normalizes discoveries into actionable Skill Sheets for domains like code, design, HR, agents.

Enables natural-language battery-cell requirements to be parsed and routed to simulation backends, returning design forms and performance metrics while supporting calibration, thermal-runaway, COMSOL, and UI draft workflows.

Provides live astronomical telemetry and space data, including ISS tracking, NASA APOD, and solar weather, via a Model Context Protocol server with SSE and JSON-RPC support.
