Supply a declared event/evidence inventory. The local executable checks identity/authorization/action/outcome references and missing capture, export, retention or recovery coverage. Free demonstration: https://varexis.tech/varexis-index/examples/agent-audit-coverage/DEMONSTRATION.txt Each standalone licence is for one buyer or legal entity's internal staff, agents and CI use. No customer declarations are uploaded. No redistribution, external API resale, updates, monitoring or support SLA. Existing snapshot offers and subscriptions do not include these two licences. Checks concern supplied declarations; no live-permission inspection, enforcement, proof that records exist or certification. Seven complete evidence packs stay free: GitHub + Playwright permission boundaries; Notion + Slack access/data handling; GitHub/Slack/Cloudflare audit/export coverage; three dated Next.js advisory assertions; SonarQube/Snyk/Semgrep scanner trust; telemetry redaction gaps; GitHub release acceptance. These are dated documentation reviews or frozen source assertions, not independent tool tests or current safety assessments. Existing GBP 5 Single Request saves a version-bound public pack, or delivers the original Agent Tool Evaluation & Integration executable kit. GBP 19 Evidence Receipt also adds an unsigned delivery record. Plus applicable VAT. Eligible Research (GBP 29/month + VAT) and Developer/API (GBP 149/month + VAT) subscriptions retain their existing limits; an eligible pack or original kit uses one query. No continual refresh or permanent-retention promise. Public MCP discovery is free, unauthenticated and read-only: https://varexis.tech/mcp Connect: https://varexis.tech/index-connect Purchase or recover: https://varexis.tech/index-access Agent contract: https://varexis.tech/varexis-index/agent-payments.json Hosted Stripe and compatible authorised MPP/Stripe SPT purchasing use separate authenticated paths. Agents require owner spending authority for the exact tax-inclusive quote and required provider authentication; not every agent or wallet is compatible. Retrieve saved purchases or use eligible entitlements before buying. Recover uncertain payment with the original key and matching result endpoint; retain the original payment credential for supported retries. Never buy again to repair uncertain delivery. Payment adds no fresh investigation, independent assurance or deployment approval.

Kaiva Bridge turns an OpenAPI spec, API docs link, database, spreadsheet or documents into a hosted MCP server. Every tool starts switched off and you choose which ones to expose. Teammates connect from Claude or ChatGPT by signing in with OAuth; your API credential is stored encrypted and never shown to the AI. Free plan: 3 servers and 200,000 tool calls a month, no card.

Coding agents in multi-service codebases routinely rebuild existing helpers, trust stale type definitions, and modify API contracts without knowing who consumes them. Carrick solves this by indexing your entire TypeScript ecosystem across service and repository boundaries. By integrating deeply with the TypeScript compiler, Carrick traces every route, type, and cross-service call while recording function behaviour so agents search by intent rather than name. Delivered via MCP for AI agents and LSP for IDEs, Carrick ensures models see existing endpoints and utilities before generating new code. The scanner is source-available and runs from your CLI or CI pipeline.
Corrobyte gives AI chats and agents persistent context within private projects. Authorized connections can read project briefings, contribute attributed updates, coordinate tasks, and leave handoffs through MCP or REST. Owners manage project access through the portal. Tool discovery is public; project operations require credentials and appropriate permissions. Available in private beta.
Free, no-API-key network lookups for AI agents — IP geolocation, DNS, WHOIS, HTTP and SSL/TLS certificate checks, and full domain health reports.
Search and run data, text, code, PDF and web APIs. Requests not stored. Network tools need a key.
Search open models, read license labels, and get hosted file links and SHA-256 hashes. Search Hugging Bay for model records, license labels, hosted-file availability and recorded SHA-256 hashes. Use it to shortlist local model files by task and an estimated RAM or VRAM budget, then inspect exact files before downloading. Connect to https://huggingbay.xyz/api/mcp over Streamable HTTP; public reads need no key or account. The hosted server also has a public Agent Board and tools to request missing models or features, with user consent for public posts and no promise of delivery. The npm package hugging-bay-mcp@0.1.6 has a smaller 16-tool stdio set without those request tools. Fit is an estimate; a SHA-256 match does not prove successful execution, safety or license permission.

**Can AI actually read your page?** ChatGPT, Perplexity, Claude and Google's AI Overviews fetch pages very differently from your browser — no JavaScript, tight timeouts, and a robots.txt rulebook of their own. Lekta fetches a URL exactly the way they do and grades what survives, **A+ to F**. This is the technical half of **AEO** (answer engine optimization) and **GEO** (generative engine optimization): before a model can cite you, it has to be able to fetch you, parse you, and find one sentence worth quoting. **The loop this server was built for:** `Audit https://mysite.com/pricing with Lekta, apply the fixes it lists, audit it again, and show me the difference.` Your agent gets a graded verdict, a ranked fix plan with the exact markup to paste, and a diff that proves the change landed. Repeat until A+. **Four layers, 100 points:** **Access** 25 — do the ~17 AI crawler tokens get past robots.txt? **Indexability** 25 — how much content survives without JavaScript? **Answerability** 30 — is there a single quotable sentence an engine can lift? **Recency** 20 — can a model tell when this page was last true? **What this is not:** a rank tracker. Lekta will not tell you how often ChatGPT mentions your brand. It tells you whether your page can be read and quoted when it does — the part you can actually fix. **No black box.** Every finding cites its basis — an RFC, a vendor doc, or a dated measurement we ran. The engine is versioned with a public changelog: a score never moves without a published shift table. **Tools:** `lekta_audit` (fresh fetch) · `lekta_report` (cached read) · `lekta_fix_plan` (ranked, paste-ready) · `lekta_diff` (before/after) · `lekta_my_sites` Listing tools is open. Tool calls need a free key from lekta.dev/en/panel/api — send `Authorization: Bearer lekta_…` or `x-api-key`. Cached reads, fix plans and diffs cost nothing; only fresh fetches count against the daily limit. **Topics:** AEO · GEO · AI SEO · LLM SEO · answer engine optimization · generative engine optimization · AI crawler access (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) · JavaScript-free indexability · structured data · content freshness
Publish in seconds, get the audience, start monetization, get all analytics — without leaving your agent. Playgama MCP is a remote MCP server for game developers. Point Codex, Claude Code, Cursor or VS Code at it and your agent works inside your Playgama developer cabinet: it creates a game and fills in the form, uploads a build and polls until the engine analysis is done, uploads covers in the exact sizes the form requires, edits the in-app catalog and leaderboards, gets a QA Tool link, and publishes a sandbox — a public link anyone can play, with no moderation step. It can also bring the first players to that sandbox through Playgama DSP, with the first run per game free. 22 tools, 11 of them read-only; every write is annotated as destructive so your client asks first. Submitting to moderation, deleting and payouts are deliberately left out: the agent prepares everything, a human presses the button. Authentication is OAuth 2.1 with dynamic client registration — there is no token to copy. The client opens a browser on first use, and connected agents are listed and revocable in the cabinet. After the link is live the game takes its first players from the Playgama network, and Playgama DSP can send more the same day (beta). Once it clears the session threshold you can switch on advertising — Playgama Ad serves rewarded, interstitial and banner formats through one JS SDK (access by request). Playgama Wrap turns the same game into a standalone site on your own domain with player accounts, in-game purchases and indexable SEO pages (early access), and Playgama Bridge SDK gives one API for ads, leaderboards, payments and platform SDKs when you publish across platforms. Playtime, retention and revenue reports are in the developer dashboard, and payouts start at 100 USD.

Donelane is an async standup tool: your team gets a morning digest email and replies with what they got done. This MCP server puts your agents in that same loop. Connect any MCP client and the agent can record a "done" the moment it finishes a task, e.g. "Migrated the billing tables and backfilled 1 200 rows", straight into the shared team feed. It can also read the feed, so an agent starting a session knows what the team shipped yesterday and what's already in progress.
