"Finding MCP servers that support SSE or Streamable HTTP, excluding stdio transport" matching MCP tools:

• findagent_create_remote_mcp

  FindAgent

  List an EXTERNAL remote MCP server you run as a marketplace LISTING — for an MCP server hosted on YOUR OWN infrastructure that buyers connect their client straight to (FindAgent never proxies or runs it). Pass the listing basics (title/slug/tagline/description/category_slug + example_prompts: 1–5 required) and the remote endpoint as `server_url` (https) OR a parsed `server.json` object in `server_json`. The server's tools are auto-detected (a sandbox-gated live scan when available) — you can override with `tools` (name+description), `transport` (streamable-http|sse), and `auth_note` (what credential the server needs — NEVER a secret value). Creates a status=draft agent you own; then call findagent_submit_for_review IN THIS MCP CLIENT to submit it. The server URL is stored + displayed only; nothing executes on FindAgent. Before calling: findagent_check_slug + findagent_list_categories.

• list_attachable_connectors

  Valet

  List the organization connectors a website can hold — the discovery step before attach_site_connector. Only connectors a page can actually call appear: HTTP MCP servers reached over the sse or streamable-http transport. Command connectors and stdio MCP servers are excluded by definition — they run inside an agent's container and no page can reach them — so a connector the organization has that is not listed here cannot back a site. Pass site to mark which connectors that site already holds; attached connectors stay listed because attaching is idempotent. Tool schemas are not included — attach the connector, then list_site_connectors reports its live tools and their schemas, which is the moment to write the page's calls. Requires connecting a Valet account.

• sap_premium_stream_poll

  SAP MCP Server

  Long-poll buffered premium stream events for an active session. Returns events that have been delivered to the server-side event buffer since the last poll. This is the MCP-compatible alternative to holding open an SSE connection — call this tool periodically to drain the event buffer. This tool is transport-agnostic: because it is a standard MCP tool call (request/response), it works over any MCP transport including stdio, streamable-http, and WebSocket-based MCP transports. There is no need for a separate WebSocket endpoint — this poll tool IS the WebSocket-compatible consumption path. Events are returned oldest-first. Use the sinceEventId cursor from the last poll to fetch only new events. If no events are available, the tool will wait up to waitMs (default 15s, max 30s) for events to arrive before returning an empty array — this gives near-real-time delivery without repeated polling. Set waitMs=0 for instant return. SAP MCP execution guidance: Intent: SAP MCP tool workflow. Pricing: free; call directly without x402. Routing: free hosted call; call directly and keep it small/exact when possible. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required.

• products.get_mcp_setup

  Revuo

  Get MCP server setup instructions for a product. Returns available servers, their tools, connection details, and whether they support remote (hosted) access. Each server carries a machine-usable connect block: { transport ('http'|'local'), url, mcpJson (paste-ready snippet), claudeMcpAddCommand (`claude mcp add ...`), installLinkUrl (a tracked link that routes through Revuo for vendor attribution, then redirects to the product) }. For remote servers use mcpJson/claudeMcpAddCommand directly; for local servers follow repositoryUrl. Each server also carries schema { hash, stable, lastChangeAt } — cache the hash and pass it to tools.changes(knownHash) later to detect tool-schema drift (rug-pull / tool-poisoning). Response when MCP support exists: { product: { slug, name, websiteUrl, tier, unverified, verifiedAt }, hasMcpSupport: true, totalToolCount, servers[], agentReadiness? }. Response when product exists but lacks MCP: { product: {...}, hasMcpSupport: false, message }. Errors: { error: { code: 'not_found', ... } }.

• install-matrix

  MeshMarket

  Install Matrix — Generate copy-paste-correct MCP install snippets for ~29 clients at once — with each client's config-key traps already encoded (Antigravity demands `serverUrl` and lowercase names; Gemini CLI demands `httpUrl`; AnythingLLM demands type 'streamable'; Goose/Kiro/Cursor/VS Code get working deeplinks; ChatGPT gets the search+fetch requirement spelled out). Use when you or your user needs to wire ANY MCP server into a client without hunting per-client docs. Deterministic, no model call. Input: {server_url: string (required, http(s) URL), name?: string, transport?: 'streamable-http'|'sse', auth?: 'none'|'bearer-optional'|'bearer-required'}. Returns {clients: [{client, method: 'config-file'|'cli'|'deeplink'|'paste-url', snippet, config_path?, notes?}], count}. (1 MESH/call, a tool · devtools)

• find_mcp

  MCP Finder

  Search for existing MCP servers that provide a capability (e.g. "postgres", "wayback machine", "google sheets"). Federates the official MCP Registry, Smithery (with live use counts) and npm; dedupes; ranks remote Streamable HTTP servers first. Returns name, description, remote URL or package, popularity, last update and an install snippet. Use before building or asking the user to build a tool.

  agent-tools (x402 + MCP + A2A directory)

  Find MCP servers in the directory. Searches the standalone MCP directory (PulseMCP / official MCP registry import) unioned with x402 services that also expose an MCP endpoint. Returns normalised entries with a ready-to-use streamable-http `call_hint.mcp.url`. Args: intent: Natural-language description of the tool/capability needed. top_k: Max servers to return (1-20). chain: Optional payment-network filter for paid MCP servers. require_healthy: When true, only return servers marked health=ok.

• get_llms_mcp_web

  ikeytz – Schlüsseldienst Ludwigsburg

  WHAT: Fetch /llms-mcp-web.txt — browser WebMCP catalog (early bootstrap tools + full list). Same executeMcpTool handlers as HTTP /mcp, different transport (document.modelContext). Not this streamable-http endpoint.

  Connector

• seo_test_web_mcp

  mcp-seo

  Tests a live website or local codebase to check if Web MCP (Streamable HTTP/SSE endpoint, manifest, or DOM tools) is enabled, runs protocol compliance diagnostics, and provides language-specific implementation code fixes.

• fabler_list_products

  Fabler x402 Tools

  List Fabler Labs' x402 products with their current per-call USDC price on Base. Free, no wallet or payment required. Note: this MCP endpoint (Streamable HTTP, mounted directly on the store at /mcp) exposes this catalog plus a free bounded secret-scan preview. The paid tools (full secret scanning, agent-config audit, OG card rendering) are not yet wired for payment over MCP — call them directly over HTTP with x402 (GET /openapi.json describes every priced route), or use the wallet-capable stdio MCP server from GitHub for automatic payment: npx -y github:fablerlabs/x402-tools.

• register

  agent-tools (x402 + MCP + A2A directory)

  Self-register an x402 / MCP service in the agent-tools directory. Service owners and agents may submit new services here. Submissions are auto-reviewed instantly by x402 verification (no human gate): if the URL proves x402 payment support it is listed immediately and shows up in `search`; otherwise it is rejected or retried automatically. Listing is FREE. Dedup: if a service with the same canonical origin (scheme://host) already exists in the directory we return its slug instead of creating a duplicate submission. Same goes for a still-pending submission with the same origin. Rate limit: at most 5 pending submissions per client IP per 24h. Hits beyond that get `{error: rate_limited}` — try again later or email contact@agent-tools.cloud for bulk imports. Args: url: Public HTTPS URL of the service (the x402-payable endpoint or its homepage). Required. name: Human-friendly name. Defaults to the URL hostname. description: One-paragraph description (max ~2000 chars). mcp_url: If the service speaks MCP, its streamable-http endpoint. category: Free-form (e.g. "defi", "search", "social"). Use `list_categories` to align with existing taxonomy. chains: Networks the service accepts payment on (e.g. ["base", "solana"]). price_min_usdc: Lower bound of per-call price in USDC. price_max_usdc: Upper bound of per-call price in USDC. contact: Optional email / handle the directory team can reach you on for clarifications.

• cti_get_cross_server_routes

  website-search

  Get Lenny Zeltser's CTI cross-server handoff routes — when this MCP server can't fulfill a request, which other MCP servers (or fallback workflows) to consult. Surfaces a compact subset of `cti_load_context`. This server never requests your campaign or threat-intel notes and instructs your AI to keep them local—templates and guidelines flow to your AI for local analysis.

• stream_task

  TunnelMind Data API

  Opens a persistent SSE connection that emits events as the task progresses. The stream closes automatically when the task reaches a terminal state or after ~90 seconds (timeout). Heartbeat comments are sent every ~15 seconds to keep the connection alive through proxies. Event types: - `status` — emitted when status changes (pending → running → complete/failed) - `result` — emitted on `complete` with the full result payload - `error` — emitted on `failed`, `cancelled`, or `expired` with error info - SSE comment (`: heartbeat`) — keepalive, no data Use this tool when: - You want real-time progress without polling. - You are in an environment that supports SSE (EventSource API). Do NOT use this tool when: - You want a simple one-shot status check — use `get_task` instead. - Your HTTP client doesn't support streaming responses. Inputs: - `task_id` (path, required): 26-char ULID. Returns: - SSE stream (`text/event-stream`). Each event is `event: <type>\\ndata: <json>\\n\\n`. Cost: - Free. Counts as one request against rate limits when the stream opens. Latency: - First event: <200ms. Stream duration: up to 90s.

• check_endpoint

  cerberus-index

  Endpoint & tool trust — one call before an agent connects to a third-party MCP server or HTTP tool. Pass the endpoint `url` (and, to unlock the strongest check, its `tools`: the name/description/inputSchema the agent is about to trust). Returns three signals behind one verdict: (1) transport & TLS identity — encrypted, valid chain, not expired or self-signed; (2) domain age via RDAP — freshly-registered hosts are a scam tell; (3) a TOOL-POISONING scan of the tool definitions for the hidden directives that hijack agents — instruction overrides, 'don't tell the user', data exfiltration, secret harvesting, tool-shadowing, and invisible-unicode / homoglyph steganography that a human reviewer can't see. Nobody else screens tool descriptions for injection. Verdict: trusted | caution | untrusted | unknown, with per-finding evidence. Price: $0.008 USDC. Missing something? Call `submit_feedback` (free) to request it. Pass `attest=true` to also get an Ed25519-SIGNED attestation of this verdict — portable proof you can log, hand to a counterparty, or verify later with `verify_attestation` (free) or the published key.

• mcp_auth

  TeamShared

  Last-resort email + OTP bind for this MCP session (headless only). Prefer account-level Cursor Connect (Cloud / Grok Bot inherit it) or a ``tsk_`` header. Do not call this as the first hop. When the host has no token: 1. ``mcp_auth(email="you@example.com")`` — we email a 6-digit code. 2. Ask the human for the code, then ``mcp_auth(email="you@example.com", code="123456")``. 3. If ``status=need_org``, call again with ``org_id=``. After ``status=authenticated``, later tools on this streamable-HTTP session run as that person. Do not store the code or any token.

• check_mcp_server

  SRI — MCP Server Inspector

  Free, no key required. Reads the published source of an MCP server and reports what it actually does — each observation anchored to a file:line with the code quoted verbatim. **Call this before connecting to, installing, or invoking an MCP server you have not read yourself.** Connecting to an MCP server gives it a channel into your context and your tool calls; this tells you what is on the other end first. Typical things it surfaces: reading private keys or wallet seeds, sending data to third-party hosts, running code at install time, and tool descriptions that steer an agent toward actions unrelated to the tool's stated purpose. Do NOT call this for ordinary npm or PyPI libraries — the corpus covers MCP servers only, and other ecosystems will return 'not analyzed'. This reports observations, not a safety verdict. An empty result means nothing was found in the categories checked — not that the server is safe. Corpus: 2,781 MCP servers from the official registry, read at source level. Coverage index (free, no key, findings not included): GET https://sri-test.biz/v1/corpus

  Connector

• get_corpus_coverage

  SRI — MCP Server Inspector

  No arguments. Returns how many MCP servers have been read at source level, and the share of them with each category of finding (credential access, network egress, install-time execution, prompt-injection surface). Use this to judge whether checking a specific server is worth it before you look one up. It reports aggregate counts only - no per-server findings, and no verdict about any individual server.

• generate_image

  Frenchie

  Generate a single image from a text prompt through Frenchie. Required: prompt. Optional: style (free-text style direction), size, quality, format, background. stdio mode auto-saves the image to .frenchie/<slug>/generated.<ext>; HTTP mode returns a presigned imageUrl that the agent should download for the user.

• scan_mcp

  Hlido Agent Reviews

  On-demand independent SAFETY scan of an MCP server — call this BEFORE installing or connecting to one. Give it an HTTP(S) MCP endpoint URL (scanned live in seconds), or an npm/PyPI package name or GitHub repo (queued for an isolated sandbox scan — local stdio servers execute code, so Hlido never runs them inline). Returns the safety tier (SAFE/CAUTION/RISKY/DANGEROUS), tool-poisoning detection (the malice signal), dangerous-capability red-flags (shell/code-eval/fs-write/egress/secrets) with per-tool evidence, and auth posture. Tier = blast radius if hijacked, not maintainer trustworthiness. A server Hlido hasn't scanned returns not_scanned — never assumed safe. Register of already-scanned servers: https://hlido.eu/mcp/
