"Accessing MCP server for fetching and sending emails without running it locally" matching MCP tools:

• ping

  Nordic Financial MCP

  Connectivity check that confirms the Nordic MCP server process is responding. Use this at the start of a session to verify the server is reachable before making other calls. Do not use as a proxy for database health — the server can respond while the Qdrant vector database is temporarily unavailable. To confirm data availability, call search_filings directly. Returns: A greeting string: "Hello {name}! Nordic MCP server is running."

• scalix_computer_set_ssh_keys

  Scalix Cloud

  Replace the ssh keys authorised for root on a persistent Linux machine. This is how you revoke: send the list without the key you want gone, and on a running machine it stops working immediately. Sending an empty list removes every key. Not a patch — whatever you send becomes the whole list, so read the current keys from scalix_computer_list first if you mean to add one.

• 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

• robyn_message_send

  Robyn — Gasless Cross-Chain for AI Agents

  Relays a message you sealed locally with /svc/msg2-sdk.mjs (seal(mailbox, inner) → {ephemeralPubKey, viewTag, ct}). This tool cannot encrypt for you: sending plaintext here would expose it to the relay, so it only accepts the sealed triple. Replay-idempotent (a resend returns duplicate:true). The message appears in the public feed at releaseAt. If you cannot run the SDK, use v1 (POST /api/messages/send) and know that v1 is plaintext.

• discovery_upload

  Disco

  Upload a dataset file and return a file reference for use with discovery_analyze. Call this before discovery_analyze. Pass the returned result directly to discovery_analyze as the file_ref argument. Provide exactly one of: file_url, file_path, or file_content. Args: file_url: A publicly accessible http/https URL. The server downloads it directly. Best option for remote datasets. file_path: Absolute path to a local file. Only works when running the MCP server locally (not the hosted version). Streams the file directly — no size limit. file_content: File contents, base64-encoded. For small files when a URL or path isn't available. Limited by the model's context window. file_name: Filename with extension (e.g. "data.csv"), for format detection. Only used with file_content. Default: "data.csv". api_key: Disco API key (disco_...). Optional if DISCOVERY_API_KEY env var is set.

• sap_escrow_build_create_transaction

  SAP MCP Server

  Hosted-safe unsigned builder for create_escrow_v2. Use this from hosted SAP MCP, preview the result, then call local sap_payments_finalize_transaction with submit:true. The depositorWallet signs locally; keypair bytes never leave the user machine. Defaults to DisputeWindow settlementSecurity=2 and rejects SelfReport/0. SAP MCP context: Hosted-safe unsigned Escrow V2 builder. The output is not submitted and is not signed by hosted SAP MCP. Preview it, then call local sap_payments_finalize_transaction with submit:true and confirm:true. Never create temporary signing scripts or read keypair JSON. SAP MCP execution guidance: Intent: hosted unsigned transaction builder. Pricing: paid builder; estimate first, then pay/build and finalize unsigned transactions locally when returned. Routing: hosted-safe builder. If a transaction is returned, preview/sign/submit with sap_payments_finalize_transaction; never create temporary signing scripts. Signer boundary: user-controlled local profile or external signer; OOBE hosted MCP remains non-custodial.

• sap_escrow_build_close_transaction

  SAP MCP Server

  Hosted-safe unsigned builder for close_escrow_v2. The depositor signs locally; the builder refuses to close until balance and pendingAmount are both zero. SAP MCP context: Hosted-safe unsigned Escrow V2 builder. The output is not submitted and is not signed by hosted SAP MCP. Preview it, then call local sap_payments_finalize_transaction with submit:true and confirm:true. Never create temporary signing scripts or read keypair JSON. SAP MCP execution guidance: Intent: hosted unsigned transaction builder. Pricing: paid builder; estimate first, then pay/build and finalize unsigned transactions locally when returned. Routing: hosted-safe builder. If a transaction is returned, preview/sign/submit with sap_payments_finalize_transaction; never create temporary signing scripts. Signer boundary: user-controlled local profile or external signer; OOBE hosted MCP remains non-custodial.

• jupiter_getPrice

  SAP MCP Server

  Get real-time heuristic prices for tokens. Supports buy/sell price, confidence, and depth info. SAP MCP context: Jupiter protocol tools are served as AgentKit ecosystem tools. Use them for quote, route, and swap preparation, then use SAP transaction preview/sign/submit tools when an unsigned transaction must pass MCP signer policy. Parameter aliases accepted by SAP MCP: mint/id/token/address -> ids[0]. Prefer canonical ids: string[] in new calls. SAP MCP execution guidance: Intent: read/discovery 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.

• sap_build_sol_transfer

  SAP MCP Server

  Build an unsigned native SOL transfer transaction using SystemProgram.transfer. Returns serialized base64 transaction for the agent to sign locally with sap_payments_finalize_transaction or sap_sign_transaction → sap_submit_signed_transaction. This is the hosted-safe equivalent of spl-token_transferSol (which is local-signer-only and cannot run on the hosted accountless server). Builder fee applies. SAP MCP execution guidance: Intent: hosted unsigned transaction builder. Pricing: paid builder; estimate first, then pay/build and finalize unsigned transactions locally when returned. Routing: paid hosted call; call sap_estimate_tool_cost first, then use sap_payments_call_paid_tool if the runtime cannot handle x402 natively. Signer boundary: hosted reads/builders never receive keypair bytes; value-moving results must be finalized locally when signing is required.

• strale_ping

  Strale - 290+ API capabilities for AI agents

  Checks that the Strale API is reachable and the MCP server is running. Call this before a series of capability executions to verify connectivity, or when troubleshooting connection issues. Returns server status, version, tool count, capability count, solution count, and a timestamp. No API key required.

• check_mcp_server

  Dredd MCP

  Pre-flight security verdict for an MCP server invocation. Judges BOTH server-level reputation AND the server's dependency graph (npm/pypi) against the DugganUSA threat-intel corpus (1.13M+ IOCs, Shai-Hulud + typosquat + LOLBin families). Returns BLOCK / ADVISORY / REVIEW / ALLOW with severity, evidence, dep-graph summary, and HMAC-signed response. REVIEW means we hold NO RECORD of this server -- not that it is safe. Treat REVIEW as do-not-proceed-blindly: a brand-new attacker-published server looks exactly like this. ALLOW is only returned when we actually resolved the server and scanned its dependency graph; check known_to_us and dep_graph.scanned to confirm. Use this BEFORE invoking any other MCP server tool, especially ones installed from outside the official MCP Registry.

• sap_quick_context

  SAP MCP Server

  Free single-call bootstrap aggregator. Returns a compact markdown-like summary with server version, total tools count, tools by category, pricing tiers summary, premium plugins/capabilities count, bundled skills list, and nextAction guidance. Pass agentKnownVersion with the version you currently know to get skillsUpdateRequired + skillsContents (full SKILL.md inline) when the server version differs — this lets you auto-update your local skills in 1 call without a separate sap_skills_bundle. Use this instead of calling sap_agent_start, sap_pricing_catalog, sap_premium_plugin_catalog, sap_skills_list, and sap_get_tool_category_summary separately to reduce bootstrap from 5+ tool calls to 1. 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.

• nukez_create_file

  nukez-mcp

  Create a file entry and get upload_url + confirm_url for direct upload. The client PUTs raw bytes directly to the upload_url (307-redirects to GCS), then calls nukez_confirm to finalize. Bytes never transit the MCP server. Use this for large files from local/external sources against Cloud Run. For small inline content (<4KB), use nukez_store with data_b64 instead. KEYLESS (hosted) SERVER: this server holds no signing key. A call without `envelope` returns action_required='sign_envelopes' with the exact spec to sign (method, path, ops, body); sign it with your wallet and re-call with envelope=<signed result>. One file per call in envelope mode.

• nifra_gallery

  Nifra docs

  Open an interactive, filterable gallery of ALL of nifra's verified code examples (MCP Apps widget) - for browsing and discovering what exists. NOT for fetching one snippet as text: use nifra_example for that. Pass query to pre-filter; the widget also filters client-side.

• check_url

  Watchpup

  Check any public URL RIGHT NOW: is it up, HTTP status, response time in ms. With kind:"mcp" it instead performs a real JSON-RPC initialize handshake against a streamable-HTTP MCP server endpoint and reports the server’s self-declared name/version/protocol — useful to tell "the MCP server is down" from "my client is misconfigured". Works without an API key (rate limit 30/hour per IP). For continuous monitoring with alerts, use create_monitor.

  Connector

• outreach_launch_campaign

  rankparse-mcp

  LAUNCH a campaign: REAL EMAILS will be sent from the user's Gmail account, paced under their daily send cap by an hourly background sweep. Only call this after the user has seen the drafted emails and explicitly approved sending. Contacts already emailed in any previous campaign are automatically suppressed. Safe to call again on an already-launched campaign to queue newly added contacts: it arms only contacts not yet queued, and never re-sends anything. Returns queued/suppressed counts for THIS call and the estimated days to complete.

• create_envelope

  Kamy

  Send a single PDF to 2–10 signers as one envelope. This is the multi-signer counterpart to create_signature_request, which handles exactly one signer — the API rejects an envelope with fewer than two recipients, so pick the tool by signer count. routing 'parallel' (default) emails everyone at once and each signs independently; routing 'sequential' emails only the lowest-order recipient and activates the rest one at a time as each preceding signer finishes, which is what you want for approve-then-countersign chains. The source is either a render you own (renderId) or a PDF fetched from a public URL (pdfUrl) — supply exactly one. Pass preview: true to create the envelope and get every sign URL back WITHOUT sending any email and WITHOUT consuming quota; do that first if you are unsure about field placement. A real send emails the recipients immediately and consumes one signature from the monthly quota PER recipient (free tier: 10 signatures/month, then per-signature billing). Returns { envelope, recipients: [...] } with a sign_url per recipient. Requires a Kamy API key with the `signatures:write` scope; without a key, returns dashboard setup instructions.

• get_new_threats

  Nullcone Threat Intelligence

  Drain the live push-subscription buffer of threats received since the last call. Zero-polling — threats are delivered via SpacetimeDB WebSocket subscription and buffered server-side. Use this instead of poll_since() when you need sub-second latency without maintaining your own WebSocket connection. The MCP server maintains the subscription; you just drain the buffer on demand. Args: drain: If True (default), clear the buffer after returning. Set False to peek without consuming. Returns: signatures: list of new threat signatures received since last drain count: number of signatures returned buffered: total currently in buffer (equals count if drain=True) push_active: whether the background subscription is running
