Generates quality control plans and inspection reports from technical-drawing PDFs: tolerances, fits, threads, GD&T and surface finishes are extracted automatically by Imnoo's drawing analysis, numbered as balloons with acceptance limits and measuring instruments, and exported as a ballooned drawing PDF, an inspection package and an Excel measurement report.

An MCP server that deterministically scores landing pages on conversion-critical signals and blocks ad spend on low-quality pages to prevent wasted budget.

A read-only MCP server for E-Hentai and ExHentai, enabling gallery search, metadata retrieval, similar-gallery lookup, tag resolution, and authenticated favorites/archive access.

Read-only access to the AI Visibility Index: the measured share of answer that 20 SaaS and 24 crypto brands hold across ChatGPT, Perplexity and Gemini, re-measured weekly on a frozen prompt panel with every past release kept at a permanent URL. Five tools — full index, one brand, brand list, complete history, methodology — served from dabyte.ai and dablock.ai with no API key and no auth; the data

Rust-native code index MCP server with first-class 1C:Enterprise (BSL) support. Static binary, no runtime — 25 MCP tools (18 universal + 7 BSL-specific), tree-sitter AST for 10 languages, federation across multiple repos.

TypeScript stdio MCP server (official MCP SDK, McpServer) for the Receipts Index. Tools: receipts_index and receipts_sample call the free /v1/index and /v1/sample routes; receipts_pricing lists the paid x402 rows. Read only; it never pays.

Per-unit cost of 13 back-office tasks done by a person vs by software, in the US, Greece and Ukraine, with an official statistic behind every hourly wage. Bundled data, works offline.

Enables mapping a company's publicly stated event presence by returning the conferences and trade shows it attends, with years, from a domain. Built on the Mamba Labs Event Presence Index actor on Apify.

Enables querying the Global Solo Banking Access Index to check which US business banking providers explicitly accept, restrict, or remain silent on applicants from 8 countries, with dated evidence URLs and provenance metadata.

Helps with cicd work, failed tests in automation and also tmmi/iso scans en reports.

Enables AI assistants to fetch today's UV index by US ZIP code or city, including EPA categories, hourly peaks, protection windows, and UV alerts from EPA and NWS data.

Enables calculation of the 2025-2028 federal overtime, tips, and senior deductions — applying IRS caps, MAGI phase-outs, and bracket tables — plus eligibility explanations and estimated federal tax savings.

Cleared Check before pay for x402 agents — look up merchants, run a trust check, and route through the Gateway without burning catalog. Tools: lookup_merchant, cleared_check, route_gateway.

On Board is a local MCP server that gives multiple AI agents and IDEs a shared project memory, ticket queue, and handoff history, so agents can seamlessly continue each other's work. It supports agent-to-agent wake events, enabling autonomous workflows like reject-fix-resubmit cycles without human relay.

Enables users to audit personal reading streams by quantifying category diversity with Shannon entropy, detecting lexical redundancy and echo chambers via Jaccard similarity, and ranking content sources by decibel signal-to-noise ratio for pruning recommendations.

Provides access to Canadian federal parliamentary data (debates, bills, MPs, votes, Hansard transcripts) and legal information (case law and legislation through CanLII) for research and analysis.

Enables users to calculate a normalized allostatic load index from biomarker panels, identify the primary vulnerable physiological subsystem, and project 12-week homeostatic recovery trajectories.

Local-first supply-chain CVE scanner. Scans project deps, system packages (Homebrew/apt), and IDE extensions (VS Code, JetBrains) via OSV, NVD, GHSA, EPSS, and CISA KEV. Listed in the official MCP Registry as io.github.DevInder1/tridentchain-security.

Enables AI agents to start, control, and verify local open.mp/SA-MP game servers via MCP stdio, using a headless RakClient to send allowed slash commands and assert round-trip responses.

MCP server for the Podcast Index API — search podcasts, track appearances, monitor trending shows, check feed health

Read-only MCP connector that serves the Run It on AI book. The index and Implementation Blocks are free; full chapters and playbooks unlock with a license key included with the book.

Enables deterministic calculation of cerebral blood-flow pulsatility and resistive indices from peak systolic and end-diastolic velocities, with classification of microvascular resistance for agent workflows.

Enables evaluation of central aortic pulse wave reflections and ventricular afterload from applanation tonometry inputs, computing augmentation pressure, AIx, AIx@75, reflection time, and SEVR for personal vascular aging monitoring.

Enables non-invasive calculation of left ventricular myocardial work indices, constructive and wasted work, and global work efficiency from echocardiographic pressure-strain loop inputs through an MCP JSON-RPC stdio interface.

A template for deploying MCP servers on Cloudflare Workers with OAuth authentication, enabling remote access to MCP tools via SSE transport from Claude Desktop and other MCP clients.

Machine-readable directory of AI products that register themselves, plus an agent-readability grader for any URL.

On-chain delivery receipts for x402 AI-agent payments on Solana: anchors SHA-256 digests of delivered content to a PDA after settlement; buyers verify proof of delivery offline with zero trust in the seller. Live MCP endpoint + npm bridge.
