Enables read-only Bitcoin blockchain queries and HD wallet derivation from xpub/seed, including balances, UTXOs, transactions, fees, mempool stats, and PSBT inspection via multiple backends with optional Tor routing.

give you access to bitcoinsAPI

MCP server giving AI agents Bitcoin and Lightning superpowers for price checks, mempool inspection, Lightning payments, and more.

Enables an AI agent to manage a Bitcoin wallet and request payments through MCP, while every spend requires a per-payment human approval code and defaults to signet.

An MCP server that tracks Bitcoin's Unspent Transaction Outputs (UTXO) and block statistics, giving AI agents direct access to essential on-chain data.

Enables interaction with Bitcoin's blockchain through Claude to embed and read data using OP_RETURN, create timestamps, deploy BRC-20 tokens, and store documents up to 100KB on-chain.

Read-only MCP server that monitors a Bitcoin Core full node via JSON-RPC, providing tools to check node status, network info, mempool, and peer information.

Provides Bitcoin and Stacks wallet operations including sending, receiving, balance checks, and transaction management via MCP tools.

Enables read-only access to Shark Exchange public kline data and Smart Money Concepts analysis for BTC across multiple timeframes, without placing orders or using API secrets.

Enables structural framing analysis of documents, identifying perspectives, omissions, and reader positioning, with numerical claim verification against authoritative sources.

Enables users to check whether a UK employer is licensed to sponsor a visa and whether a salary meets Skilled Worker thresholds, drawing on the official Home Office register of licensed sponsors and published GOV.UK salary rules. Exposes read-only tools for sponsor verdicts, fuzzy employer search, salary checks, and register metadata from Claude or the command line.

Enables AI coding agents to audit Supabase or Postgres databases for Row Level Security and multi-tenant isolation holes, reading tables, grants, policies and functions for static findings and optionally probing those policies inside a rolled-back transaction. It reports each hole with an explanation and a fix, so an agent can verify the migrations it just wrote before declaring them done.

Enables deliverable conformance and evidence-chain checks by turning requirements into executable specs, validating numbers against a provenance ledger, and auditing PDF/OOXML metadata and archive manifests.

MCP server that lets agents check domain email authentication (SPF, DKIM, DMARC, MX) via a free API, returning grades and shareable report URLs. Also provides tools for listing paid services and partner program terms.

Enables AI listing assistants to validate marketplace draft listings against seller-provided item specifics, returning PUBLISH or REVIEW with the exact words behind every unbacked claim.

Enables AI coding agents to retrieve the latest stable versions of packages and tools across multiple ecosystems, preventing outdated dependency versions in generated code.

Free open-source CLI and read-only MCP tool from Advisors AI (advisorsai.ai): give it one public URL and it lists which machine-readable basics are present or missing (title, meta description, structured data, one h1, canonical, robots policy for AI crawlers, llms.txt, sitemap). No API key, no account, nothing stored.

Enables AI agents to validate a Japanese qualified invoice against the six required items, reduced-rate markings, per-rate totals, and once-per-invoice-per-rate tax rounding, while flagging the common line-by-line rounding mistake, and to normalize and verify T + 13-digit registration numbers. Read-only tools also compute expected consumption tax for a given amount, rate, price basis, and rounding method.

The first MCP Server dedicated to Bitcoin ecosystem

Enables AI agents to query the free official UK Companies House registry through four tools: searching companies by name, retrieving merged profiles with status, registered office, SIC codes, and current officers, pulling filing history, and decoding any UK SIC code to plain English offline. It runs on a free API key (and still starts without one), caching responses to keep repeat lookups cheap for prospect research, KYB, and due-diligence workflows.

Enables an AI agent to verify its draft answer against supplied sources sentence by sentence, flagging unsupported figures, dates, citations, and must/may wording and offering source-backed corrections. An optional judge mode can additionally assess prose via a configured LLM endpoint, while default operation is deterministic and offline.

MCP server that checks a website's AI-search (GEO) readiness: robots.txt access for 16 AI crawlers (GPTBot, OAI-SearchBot, PerplexityBot, ClaudeBot, Google-Extended, Bingbot...), JSON-LD schema, llms.txt, sitemap and basic SEO tags. Python, stdio, MIT.

Scans markdown vaults to detect contradictory claims (quantitative and negation) between notes with high concept overlap, and provides tools for analysis and reconciliation.

MCP server that exposes 31 OSINT checks from Lissy93/web-check as tools for website analysis, including SSL, DNS, headers, WHOIS, and security presets. Enables natural-language-driven web recon and health checks.

MCP server for checking domain name availability across 500+ TLDs using RDAP with WHOIS fallback for specific TLDs.

MCP server for verifying Russian counterparties (legal entities and individual entrepreneurs) via public Federal Tax Service data: EGRUL/EGRIP, bankruptcy registry (EFRSB), Transparent Business, bailiff service (FSSP), and arbitration courts (KAD).
