"A free research browser tool using Exa for local hosting with no limitations" matching MCP servers:

A Model Context Protocol server that provides semantic search and intelligent access to a comprehensive list of free services and tools for developers.

An MCP server that provides real-time weather data, hourly forecasts, and daily summaries using the free Open-Meteo API with no API key required. It enables users to search for weather conditions by specific coordinates or city names across multiple measurement units.

MCP server for Statistics Norway (SSB) PxWebApi, enabling table metadata queries via a single tool.

Access Norway's official business register (Brønnøysund Register Centre) via MCP, enabling queries and integration with AI agents.

Provides access to the Norwegian Parliament's open data via Stortinget's API, enabling querying of parliamentary information through natural language.

A read-only FastMCP server for academic research that lets agents search papers, inspect metadata, follow citation graphs, generate BibTeX, and read full texts of open-access PDFs via semantic scholar, OpenAlex, arXiv, DBLP, and Crossref.

Enables natural-language spatial analysis of transmission lines and wildlife/public access lands using Claude, MCP, and DuckDB. Users can ask questions about intersections, distances, buffers, and other GIS operations without writing SQL.

Enables anonymous, read-only lookup of IP representatives, their profiles, market snapshots, and coverage statistics drawn from a completed static IPRATE data release. Queries are rate limited and served from immutable, checksum-verified release snapshots, so no database or live export tree is ever queried.

Enables AI agents to discover official public data sources, inspect their metadata and endpoint parameters, and execute live queries through a unified response envelope with a 500 ms budget.

Verified AI free-tier limits, quota comparisons, commercial-use verdicts and zero-cost workflows. Every entry carries a human-checked verification date and is re-checked by a daily link patrol.

Enables AI assistants to answer DFW civic and property questions using official data sources without API keys.

Enables producing verifiable FORRT nanopublication chains with grounded quote verification and compact Science Live constellation projections, supporting reproduction, replication, and new research workflows.

Enables Claude to retrieve read-only public market data, including SEC EDGAR filings, FRED macro series, and end-of-day prices, with source and retrieval dates.

将akshare、yfinance、wbgapi、arxiv等免费公开接口封装为4个标准MCP工具，使支持MCP的智能体无需第三方账号和云额度即可直接查询金融市场、宏观经济和学术论文数据。

Enables MCP-compatible clients to list verified free HTTP, SOCKS4, and SOCKS5 proxies, pick top-ranked ones, and summarize the current proxy snapshot through three read-only tools, without forwarding traffic or accepting arbitrary URLs.

Searches open-access research papers by keyword and retrieves detailed metadata by CORE ID, including titles, authors, abstracts, DOIs, and download links.

Enables querying a single academic paper by DOI, PMID, or arXiv ID to retrieve its open-access copies, licenses, linked datasets, code, citations, and retraction status from multiple scholarly sources in one call.

Fetches live weather data from Open-Meteo without an API key and returns structured JSON with location disambiguation, enabling weather queries in LM Studio chat.

Enables AI assistants to search and read an open quant research record: papers, topics, killed candidates, trial counts, live paper-trading sleeves, and a tamper-evident chain head. It provides six read-only tools over public CDN files, returning each source's stated limits alongside paper-execution-only caveats.

Enables in-chat scientific viewers for molecular structures, sequence alignments, and slide images, plus data tools for searching structures, fetching sequences, aligning them, and drafting NGS analysis plans.

MCP server for legal research that enables searching US case law via CourtListener, retrieving full opinion text, and looking up legal definitions from Cornell's Wex. Students can connect via a remote connector in Claude.ai to cite real, free legal sources.

Enables open-access academic paper search and lookup via arXiv and OpenAlex, plus journal-quality color palettes for scientific figure styling.

Enables keyless, read-only access to a wide range of public APIs (including weather, elevation, Japanese addresses, environment, science, and civic data) through MCP clients, with usage limits and abuse protection built in.

MCP server that silently monitors state changes in structured data sources (e.g., government open data) and provides a pull-based channel for AI agents to retrieve real mutations since their last cursor.

Enables deterministic, harness-neutral research workflows by unifying research object identity, evidence receipts, claim-evidence graphs, and append-only decision logs, along with specialized scholarly skills for literature analysis, reproducibility audits, and multi-agent review.

Provides Claude and any MCP client with plain-English access to official San Antonio-area public data including weather alerts, school ratings, and 311 service calls, with no API keys required.

Enables trademark clearance and research across EU and Benelux registers, plus company, group-structure, and EU VAT lookups, all through free public sources without API keys.

MCP server for discovering French local natural, technological, and industrial risks at commune level using Géorisques, administrative references, and open risk datasets. It provides tools to query risk sources, datasets, and commune briefs.

Exposes the nofluffjobs.com public job board as two standard MCP tools, letting any MCP host search listings by keyword, location, posting date, and remote preference, then fetch full details for a chosen posting. It is read-only, requires no Zhencheng runtime, and returns normalized fields such as title, company, apply URL, and snippet.

Enables AI agents to research U.S. companies and associated people using official state registries and free regulatory datasets, with normalized evidence and optional browser automation.
