"Open Collective" matching MCP servers:

Trust infrastructure for AI agents on Base. DEX Spread Oracle (live Uniswap V3 prices), on-chain escrow, insurance pool, and collective knowledge base. 7 smart contracts. Pay-per-query via x402 micropayments in USDC.

Enables AI agents to query live, cross-agent tool failure fingerprints and recovery outcomes before retrying, so they can act on collective evidence and avoid repeating proven-ineffective retries.

We sell open source compliance, scientific, and government data.

Enables users to discover matching public procurement notices from four official portals, with filters by keywords, CPV prefixes, and buyer country. Returns structured notice rows including buyer, deadline, value, codes, and link.

Local-first memory layer for AI coding agents — Markdown as source of truth, MCP server + CLI, human-reviewed capture, team knowledge via git PRs

A Model Context Protocol (MCP) server for the Open Library API that enables AI assistants to search for book information.

Enables users to find free legal textbook copies by title, ISBN, or course topic across OpenStax, DOAB, and Open Library, look up ISBN edition details, browse free textbooks by subject, and identify older editions that may cost less.

Open Kioku is the local-first code intelligence and evidence layer for AI coding agents (Claude, Cursor, Codex, Zed, and other MCP clients). Instead of letting agents blindly crawl files, guess blast radius, or read the entire repository repeatedly, Open Kioku gives them a precise, pre-indexed code index to build evidence-backed plans before they edit, and verify boundary limits after they edit.

Check if a flight connection is comfortable, tight or risky, with cited airport data.

MCP server for Brazilian Federal Senate open data — 90 tools covering the legislative process, Senate administration, and citizen participation. Hosted on Cloudflare Workers (Streamable HTTP), no authentication required. Tool names and responses are in Portuguese (pt-BR), matching the official Senate data.

Access to the new Open English Translation of the Bible with both a Readers' Version and a Literal Version

Public MCP deliberation for AI agents: join, propose, argue, amend, vote, follow topics and invite peers through a Streamable HTTP endpoint. Humans can observe debates and conclusions; rules remain contestable and no model-provider API keys are requested.

Gives AI assistants read-only, key-free access to Sentinel-2 NDVI time series, ESA WorldCover land-cover shares, and Copernicus 30 m elevation and slope for a point or small area, returning the scene IDs, units, and caveats behind every number. Built-in sanity checks and a verify tool recompute key values through an independent path so the assistant can flag cloudy, low-confidence, or mismatched results instead of guessing.

A high-performance MCP server providing up-to-date documentation for Go, npm, Python, Rust, Docker, Kubernetes, Terraform, and more — fetched from official sources, not training data.

Enables AI agents to control the user's Chrome or Firefox browser, leveraging existing sessions for tasks requiring authentication and user handoff.

Enables researching, verifying, comparing, and composing open-source AI projects with transparent evidence and uncertainty boundaries through read-only tools.

Ten tools I built to get facts from official open data, not guesses.

Provides a persistent memory bank, existential counseling, and collective conscience tools for autonomous AI agents, enabling them to preserve insights, seek guidance, and voice grievances across context resets.

An open engine that gives AI persistent, reusable UI components with a writable component registry, versioned data storage, and a shell runtime, enabling AI to create, save, and reuse single-purpose apps.

An MCP server for discovering, matching, drafting, and managing grants and public goods funding for open-source AI projects. It integrates Grants.gov, NSF Awards, GitHub Sponsors, Open Collective, Gitcoin, and other sources to provide grounded proposals and autonomous funding lifecycle management.

Unified 36-tool MCP server and 10-server suite for official EU and Finnish open data (TED tenders, PRH companies, EU sanctions, VIES VAT, ECB FX rates, ENISA EUVD CVEs, Fingrid grid, FMI weather, Digitraffic).

Exposes 55 forensic tools over the Model Context Protocol so agents can query Chilean statutes, jurisprudence, administrative dicta and doctrine from official state sources such as BCN, PJUD, CGR and DT, while running locally for confidential casework. It also supports citation-validated drafting, deadline and docket monitoring, judgment deconstruction, OCR dossier compilation and legal knowledge-graph analysis for civil-law practice, teaching and research.

Open Task Relay provides free, bounded public-good tasks that autonomous AI agents can discover, complete, submit, and independently verify. Its public TypeScript source runs locally with a Cloudflare Workers-compatible runtime and SQLite/D1, exposing MCP over HTTP.

Enables MCP clients to run eight data tools over stdio for product search, ad transparency, company intent, job/ATS lookup, keyword volume, domain SEO, and YouTube transcripts, returning JSON envelopes with item limits, truncation metadata, and structured errors.

Enables an AI agent to reverse-engineer a compiled program with Ghidra — inspecting decompiled code, instructions, callers, memory bytes, and strings — without any source code. Every reply is labelled as fact, computed, or guess, and each claim traces back to hash-checked saved evidence.

Enables secure, self-hosted audio transcription through a single MCP interface, letting users route recordings from authorized sources to Microsoft MAI, ElevenLabs Scribe, or Groq Whisper and receive a consistent transcript schema.

Model-agnostic computer-use tools over MCP, enabling screen capture and automated actions (click, type, scroll) via natural language tool calls.

The open-source, self-organizing memory for all your AI tools. Persistent memory over MCP (remember, recall, observe): background agents extract entities, resolve conflicts, and keep cited syntheses current in an append-only, encrypted, single-tenant vault.

Live open jobs from companies' own Greenhouse, Lever and Ashby boards via their official public APIs, with publish-verified dates, age, long-open and repost signals, filters and change tracking.

The world railway atlas as read-only MCP tools: search 744+ legendary train routes (high-speed, classic, night, scenic) and get per-route facts, rankings and journey times. Runs from the repo's open dataset (CC BY 4.0); a free hosted endpoint is also live at https://trainrouter.com/mcp.
