"Gathering Context from an Ubuntu Server" matching MCP tools:

• lyra_cancel_gathering

  lyra-mcp-server

  Mark a gathering as cancelled. Works from any non-terminal state (draft, awaiting_responses, live, rescheduled). Records the cancellation reason in the audit log if provided. Already-issued invites stay in the database (audit trail) but the RSVP page will show the gathering as cancelled. Requires API key authentication.

• verify_receipt

  TrustBench

  Verify the Ed25519 signature on a TrustBench receipt. Two modes: (1) Lookup mode — pass receipt_id and the server fetches the receipt from trustbench.io and re-runs verification (handy when you only have an ID). (2) Offline mode — pass receipt_json (the full {receipt, signature} envelope an agent received from a third party) and the server verifies the Ed25519 signature against the published public key at trustbench.io/.well-known/trustbench-pubkey without trusting the database. Exactly one of receipt_id or receipt_json must be provided. Output: returns JSON with receipt_id, signature_valid (boolean), on_chain_verified (boolean, where present), signature_alg ("ed25519"), verify_url, pubkey_url. For non-server-mediated verification with no network round-trip, use the @trustbench/verify-receipt npm package.

• switch_dannet_server

  dannet

  Switch between local and remote DanNet servers on the fly. This tool allows you to change the DanNet server endpoint during runtime without restarting the MCP server. Useful for switching between development (local) and production (remote) servers. Args: server: Server to switch to. Options: - "local": Use localhost:3456 (development server) - "remote": Use wordnet.dk (production server) - Custom URL: Any valid URL starting with http:// or https:// Returns: Dict with status information: - status: "success" or "error" - message: Description of the operation - previous_url: The URL that was previously active - current_url: The URL that is now active Example: # Switch to local development server result = switch_dannet_server("local") # Switch to production server result = switch_dannet_server("remote") # Switch to custom server result = switch_dannet_server("https://my-custom-dannet.example.com")

• recall

  Seatgeek

  Retrieve a value previously saved via remember, or list all saved keys (omit the key argument). Use to look up context the agent stored earlier — the user's target ticker, an address, prior research notes — without re-deriving it from scratch. Scoped to your identifier (anonymous IP, BYO key hash, or account ID). Pair with remember to save, forget to delete.

• atlas_create_jd

  CareerProof MCP

  Create a job description from text within a hiring context. Returns a JD object with 'id' and stored content. Use JD content as jd_text in atlas_fit_match, atlas_fit_rank, atlas_start_jd_fit_batch, and atlas_start_jd_analysis. Requires context_id from atlas_create_context or atlas_list_contexts. Free.

• search_balanced_news

  Helium MCP Server - News, Markets & AI

  Search Helium's balanced news stories — AI-synthesized articles that aggregate multiple sources. Unlike search_news (which returns individual RSS articles), this returns Helium's own synthesized stories: each one draws from multiple sources and includes an AI-written summary, takeaway, context, evidence breakdown, potential outcomes, and relevant tickers. Returns a list of stories, each with: - title, simple_title, date, category - page_url: full URL to the story on heliumtrades.com - image: story image URL (when available) - summary: Helium's synthesized overview - takeaway: key conclusion - context: background context - evidence: numbered evidence items - potential_outcomes: forward-looking outcomes with probabilities - relevant_tickers: related stock tickers - num_sources: number of source articles synthesized - rank: search relevance score Args: query: Search keywords (required). limit: Max results (1-50, default 10). category: Filter by category. One of: 'tech', 'politics', 'markets', 'business', 'science'. days_back: Only include stories from the last N days. 0 means no date filter.

• vf_health

  VoiceFlip

  Returns VoiceFlip MCP server health and version metadata. No authentication required. Use this first to verify the server is reachable from your MCP client.

• tronsave_get_min_price

  Tronsave MCP Testnet

  Quote the minimum unit price for a buy. Returns `{ minPrice }` (SUN per resource unit) from GraphQL `market.estimateMinPrice` for the given `resourceType`, `buyAmount`, and `durationSec`. Optional `address` scopes context when the API supports it. No login required; an optional session forwards auth like `tronsave_list_order_books`. Read-only and idempotent. Pair with `tronsave_estimate_buy_resource` for full buy quotes and `tronsave_list_order_books` for depth buckets.

• ping

  nara-tour

  Connectivity check — returns server version and current timestamp. Use to verify MCP server is reachable before calling other tools.

  Connector

• lyra_create_gathering

  lyra-mcp-server

  Creates a new gathering in 'draft' state with optional proposed time slots and invitees. The agent-driven flow is: propose attendees → check availability → call create_gathering with the user's intent + 2-3 slot candidates + invitee contact_ids. Status starts as 'draft' until lyra_finalise_gathering locks the slot. Requires API key authentication. NOTE: All free-text fields are user-generated.

• simulate_mmc

  QueueSim

  Run a generic M/M/c queue simulation. Provide an arrival rate (λ, arrivals/hour), a service rate per server (μ, customers/hour each server can finish), and a server count (c). Optional: distribution shapes, service coefficient of variation, run length. Returns per-hour metrics and an overall summary (avg wait, queue length, offered load, throughput). This is the primary tool for 'how many servers do I need?' / 'what's my average wait?' style questions. ALSO preferred over simulate_scenario for what-if questions about scheduled scenarios (Coffee Shop) when the user wants flat uniform numbers — pull the peak params from describe_scenario and run them here. That usually matches user intent better than collapsing a schedule. ANTI-FABRICATION: the returned numbers come from a real discrete-event simulation run. Quote them VERBATIM in your reply. Do not round, estimate, or compute derived figures from training-data recall. If the user asks a follow-up about the same configuration, re-call this tool rather than recalling numbers from earlier in the conversation.

• lyra_reschedule_gathering

  lyra-mcp-server

  Move a live gathering to a new time (and optionally a new venue). Transitions the gathering to 'rescheduled' state. Already-accepted invitees have their RSVP status reset to 'invited' so they re-confirm at the new time. Appends a gathering_rescheduled event to the audit log with both old and new slots. Requires API key authentication. To cancel instead, use lyra_cancel_gathering.

• interpret_result

  QueueSim

  Given an M/M/c configuration (arrivalRate, serviceRate, servers) and optionally an observed average wait, returns a queueing-theory framed interpretation: where you sit on the utilization curve, what ρ means in plain language, what one more or fewer server would qualitatively do, and which complexity factors (priority, abandonment, skills routing) might be hiding in real data the M/M/c model can't see. Use this to TEACH while answering — when the user wants context around a number, not just the number itself. Pure text computation, no simulation, no RNG — deterministic output.

• images_prepare_upload

  Roboflow (Official)

Use candidate id as candidate_id in atlas_start_gem_analysis, atlas_fit_match, atlas_fit_rank, atlas_generate_interview, and batch tools. Requires context_id from atlas_create_context or atlas_list_contexts. Free.
