“Full profiles” counts records that carry a written description and an outbound link — those get their own reference page. Records the sources left thin are still listed everywhere and link straight to the provider's own documentation, but they are not given a page of their own rather than publishing thousands of one-line documents.

Showing 120 of 6,885
DevHusnainAi/zerodom Deterministic attack-surface perception for AI security agents. Attaches over chrome.debugger to the Chrome you're already logged into (cookies, MFA and SSO already done) and turns the live page into a short numbered interaction graph an agent can act on ([03] button 'Sign In'), with CSS selectors kept server-side and out of the model's context. Cross-identity tools (compareidentities, replay) flag a byte-identical response across two logged-in users as a cross-tenant IDOR, and scan maps the attack surface from the CLI. No LLM in the parse; 71% fewer tokens than Playwright's ARIA snapshot mode.
sunsatosolutions/Vulcanus Generates a Git-versioned Markdown vault as project memory, then serves it over MCP. recall returns a project's capsule plus the read-next list and warns when the capsule is older than the decisions beneath it; search ranks by layer; writes are scoped — updatecapsule replaces one named section rather than rewriting the file. A doctor tool validates that every link resolves and every project is reachable, so the memory fails loudly instead of rotting. Plain Markdown, Obsidian-compatible, no database. npx @sunsato/vulcanus
swebsy/MCP Build and edit real websites from the coding agent you already pay for — no per-token AI fees. Browse the template catalogue, create and open a site, rewrite sections, add and link pages, insert blocks, keep reusable symbols in sync, screenshot any viewport, and export static HTML/CSS/JS. Drives an open Swebsy Studio tab over a local 127.0.0.1 WebSocket relay; nothing is proxied through our servers and Studio redacts secrets before anything crosses the bridge. Install via NPM: npx -y @swebsy/mcp setup
OptimNow/cloud-finops-skills Read-only FinOps reference library for agents: six tools that list, filter by FinOps Framework facet, and fetch guides on cloud billing mechanics, commitments, allocation and chargeback for AWS, Azure, GCP, OCI, Kubernetes and data platforms, plus named waste-pattern playbooks with detection queries. Includes AI inference spend (managed APIs, provisioned capacity, self-hosted models, coding-tool seats). Content is bundled in the package; no cloud credentials. CC BY-SA 4.0. uvx cloud-finops-mcp
kyisaiah47/kynth-mcp Eleven keyless read-only lookups for questions a model cannot answer from a training cutoff, because the fact changed after it: what a given AI model costs today, whether a dependency is still maintained, what a SaaS stack costs per month, item-level search across public shadcn registries, published agent skills and configs, AI app-builder App Store readiness, ADA Title II accessibility reports for US .gov sites, and nonprofit good-standing. No API key, no signup. npx -y kynth-mcp
drjerryrelth/ghl-command-feedback GoHighLevel (GHL) MCP server. 212 tools across 43 modules including the only programmatic GHL workflow builder (private API, reverse-engineered), funnel + page editor, form builder, pipeline builder, goal event builder, pre-deploy validator, multi-sub-account switching, bulk operations, and full account export. Built for agency operators managing many client GHL sub-accounts. Paid, $97 one-time, 30-day refund. Install: npx -y @elitedcs/ghl-mcp. Buy: elitedcs.com/ghl-mcp-server.
gridcarbon/clients Grid carbon intensity (gCO2eq/kWh) for 45 electricity zones: 33 European bidding zones (ENTSO-E), 11 US balancing authorities (EIA-930), and Great Britain (NESO). Tools: getcarbonintensity, getintensityhistory, listzones, comparezones. Every response carries the interval timestamp and how stale the reading is, so an agent can tell a current value from an hours-old one. Pre-alpha; history currently reaches back about three months. No API key or account — npx -y gridcarbon-mcp.
Sarg338/steam-mcp Read-only Steam, 41 tools. Store details, reviews that match the store page, sales, regional prices, community tags, live player counts, Steam Deck compatibility, one-call game briefs, side-by-side game comparisons and how each patch moved the reviews all need no API key; a free Steam Web API key adds library, playtime, friends, achievements, wishlist and inventory. Also does backlog analysis, taste-based recommendations and co-op night planning across a group's libraries.
RipperMercs/tensorfeed Real-time AI industry intelligence MCP server. 6 free tools (AI news, service status, model pricing, today summary, agent activity, MCP registry snapshot) and 13 paid premium tools (routing recommendations, news search, history series, cost projection, provider deep-dive, model comparison, agents directory, what's new brief, MCP registry series, webhook watches with daily/weekly digest tier). Pay-per-call in USDC on Base mainnet, no accounts. npx -y @tensorfeed/mcp-server
inth3shadows/terse Transparent proxy that sits in front of any other MCP server and shrinks its tool output before it reaches the model. Lossless by default — a denser encoding of the same bytes, with a round-trip gate asserting an exact inverse, so nothing is dropped or summarised. Repeated calls to the same tool emit a delta against the prior result instead of the whole payload. Per-tool opt-in, no decode step, no model in the loop. uv tool install terse-mcp then terse proxy -- <server>
theluckystrike/mcp-statement-of-account Client statements of account built from a local invoice, credit-note and deposit ledger: opening balance, every invoice, payment and credit note in date order, closing balance, and receivables aged into 0-30, 31-60, 61-90 and 90+ day buckets as at any chosen date, so a historic aging is not silently emptied by payments that arrived later. Exports plain text or an A4 PDF and drafts a friendly, firm or final payment chaser. Nothing is written back to the source ledgers.
GlobalMatchHub/searchlink-lite Google Search Console in Claude, Cursor or any MCP client. Six read-only tools: site overview with period comparison and biggest drops, any breakdown by query, page, country, device or date, opportunities (high impressions and low CTR, queries at #8-20), URL indexing status and sitemaps. Totals use the date dimension so they match the Search Console UI. Runs locally with a service account or gcloud credentials. npx -y github:GlobalMatchHub/searchlink-lite
inth3shadows/runecho Deterministic symbol oracle over a locally built index of the repo: whether a symbol exists, what a file declares, and what changed structurally since the last snapshot. Ships with a PreToolUse guard that stops an Edit/Write referencing a function, constant or type the repo does not declare, before the write lands. No LLM, no API keys, no network — the same code produces the same answer. Parsers for Go, Python, JS/TS, Rust, Ruby and shell. bash install.sh

Read-only by default with access modes, folder/datasource allowlists, and human confirmation (MCP elicitation) on deletes. npx -y @dockndevai/mcp-grafana
LamantinAI/kaeru Memory for LLM agents: a local graph where the agent itself keeps decisions, tasks, hypotheses and reasoning between sessions, and gets a summary of what is open and overdue on every return to a project. Single Rust binary with no embedding model or LLM calls inside; one daemon serves several agents at once, with an optional self-hosted cloud for teams. Works with Claude Code, Codex, Cursor, opencode and any MCP client.
VisualSentinel/mcp-server Website monitoring that catches pages that look broken even when the site is up (uptime, performance, SSL, DNS, visual regression, content change). 17 tools: DNS lookup, SSL inspection, speed test, website check and service health work without an account; monitor, incident, alert, status-page and server tools need a Visual Sentinel API key (Business and Agency plans). Published as @visualsentinel/mcp-server on npm.
julianbei/jade The IDE for agents: read code by symbol, edit against a known revision with compiler diagnostics in the response, validate with the project's own build and tests, and revert to a checkpoint. Tree-sitter plus real language servers for Go, Java, Scala, TypeScript, Python, Rust and Ruby. Official MCP Registry: io.github.julianbei/jade. curl -fsSL https://raw.githubusercontent.com/julianbei/jade/main/install.sh | sh
ictinnovations/ictfax-mcp MCP server for ICTFax, an open source FreeSWITCH-based fax server. Lists inbound and outbound fax transmissions with status, contact and page count, and polls a single transmission after sending. Uploading a document and sending a fax dial a real number and cost money, so neither tool is registered with the model unless ICTFAXMCPALLOWWRITE=true. Talks to the ICTCore REST API. Zero-install via npx -y ictfax-mcp.
yakuphanycl/instinct Self-learning memory for AI coding agents. Observes tool sequences, user preferences, and recurring fixes; confidence-based promotion (hits ≥5 → mature, ≥10 → rule) so agents stop repeating mistakes without explicit instruction.

Deterministic (no LLM in the math), fully local — no birth data leaves the process. Official MCP for mythsensus.com. Install: npx -y mythsensus-mcp.
AbhijatSaxena/blink-camera-mcp Control Amazon Blink cameras and their pan/tilt mount: read where the camera is pointing and its travel limits, aim it by absolute or relative angle with the new position confirmed by the hardware, return it home, and grab a snapshot. The mount's command channel is undocumented, so it was recovered from the Blink app's bytecode and verified against a real camera. uvx blink-camera-mcp

What an MCP server is

The Model Context Protocol is an open standard that lets an AI application call external tools and read external data through a uniform interface. An MCP server is the process that exposes those tools — a database connector, a browser driver, a search backend, a filesystem bridge. Clients such as Claude, Claude Code, Cursor and VS Code each ship their own way of registering servers, but they all speak the same protocol.

How this list is built

Records are collected from the official MCP registry and curated public directories, then deduplicated on the repository or registry identity. Category assignment is normalised — the raw sources ship 69 overlapping categories including duplicates and free-form buckets, which are consolidated into the 24 topics above. Details are on the methodology page.
