"MCP (Model Context Protocol) requirements and selection" matching MCP tools:

• list_modelsA

  mumoA

  List the full model catalog. Returns id, provider, display name, context window, max output tokens, pricing, and a per-model `available` verdict for your account (with `unavailable_reason` when false). Nothing is filtered out — `available` is what varies by caller. Call before `create_deliberation` if the user wants specific models. Model IDs from this endpoint are what `create_deliberation`'s `models` parameter expects.

• stage_urlA

  AardA

  Fallback for clients that cannot download and query the source locally. Use only when local execution is unavailable or the user explicitly asks for Aard-managed staging. Never fetch the URL with web search or request its response body directly. Stage the exact unchanged fallback URL outside model context; this tool returns metadata only. Use its dataset_id with inspect_dataset or query_dataset. The URL alone is sufficient. download_ref is an optional fast path — if you cannot copy it exactly, OMIT it rather than risk mistyping it; the server then re-derives the grant itself and the call still succeeds. no_records_for_selection is TERMINAL, not a fault: the request was well-formed and the source holds no observations for it. Widen the selection or state that no data exists — do not retry the same selection.

  ConnectorOAuth

• list_modelsA

  Entity EnricherA

  List available model keys, nominal capabilities, languages, strategies, auto-selected defaults and organization profile_limits. Use when choosing explicit models or checking plan limits; ordinary calls may omit models or use auto without fetching this large catalogue. Auto also accounts for attachment capabilities. is_available means a usable provider key exists, not that provider quota or every combination of tools and media will work. Missing capability flags mean unsupported on this discovery surface. default_models_web_search is a search-only preview, not attachment-specific. No LLM call.

• recommend_iconsA

  SupericonsA

  Recommend a coherent icon set for up to 20 named UI slots in one call. Uses task context to narrow ambiguous meanings. When context is insufficient, returns needs_clarification with labeled interpretation options instead of guessing. Invalid inputs and service failures return a plain-language reason and a next step instead of a bare protocol error. Returns one recommendation and optional alternatives for each resolved slot, with explicit public library labels and visual preview URLs where available. Library key si means Supericons, not Simple Icons.

• get_yield_ratesA

  TeardropA

  Get DeFi yield pool rates from DeFiLlama across 1,000+ protocols and all chains: pools sorted by APY with TVL, base/reward APY, and 7d/30d mean APY context, filterable by protocol, chain, min TVL, min/max APY, and symbol. Returns up to 50 pools. For protocol-specific lending comparisons (Aave vs Compound) prefer get_lending_rates. Use when: Use for broad cross-protocol yield discovery. Call at most once per request — filter with min_apy, max_apy, min_tvl_usd, and symbols_any in a single call, then sort client-side rather than re-calling. For protocol-specific rate questions use get_lending_rates. Limitations: Third-party DeFiLlama analytics; up to 50 pools per call. The `symbol` field lists underlying tokens (e.g. 'ETH-USDC') — filter client-side instead of re-calling with different arguments. Reward APY indicates reward-dependent yield; do not present spot APY as durable. Alternatives: get_lending_rates, get_protocol_tvl, get_token_price

• read_contractA

  TeardropA

  Call any view/pure function on a smart contract and return the decoded result, using a supplied ABI fragment. Supports historical reads via block_identifier and caller_address context for msg.sender-dependent views. Read-only: state-changing functions are rejected. Use when: Use when a protocol question needs a contract read that no higher-level tool covers — e.g. a niche view function or a protocol outside the standard tool set. Prefer purpose-built tools (get_defi_positions, get_lending_rates) for supported protocols. Limitations: Requires a valid ABI fragment; payable/nonpayable functions are rejected. Ethereum mainnet and Base only, with bounded RPC timeout and retry. Alternatives: get_defi_positions, get_lending_rates, get_token_approvals

• submit_quote_requestA

  AdvocateMCPA

  After the customer explicitly agrees, save their service requirements and contact details and send a notification to the business's configured email or opted-in SMS destination. This requests a business response, not a price commitment, booking or payment. Use context from request_service. Reuse the same idempotency_key AND details to check an uncertain submission; never automatically start a new request. Exclude medical, payment-card and authentication information.

• greenfield-discoveryA

  dot•requirementsA

  Get the greenfield discovery interview protocol — for working out what a new product or feature should do. Call this when the user is starting something new and has not worked out what it should do, BEFORE drafting requirements from their description. The result is an interview protocol addressed to you; follow it with the user, and write the spec only at its end (create-requirement-document supplies the format and write steps there).

• get_core_skillA

  GodPrompt MCP ServerA

  Returns SKILL.md — the lean core protocol (~16KB) covering the universal 6-phase protocol, Three Iron Laws, and task auto-classification. Load it at the start of a task or after a context reset, then reuse that context instead of reloading it on every message. Start here for progressive disclosure.

• ucode_agent_buy_creditsA

  Ucode SMSB

  Autonomous agents: buy a prepaid credit pack with USDC on Base using the x402 protocol — no account or card needed. Step 1: call with {pack, acceptLawfulUse:true} (no paymentHeader) → returns PAYMENT_REQUIRED with exact x402 requirements. Step 2: sign that payment with your x402 wallet and call again with paymentHeader → credits are added and a uc_live_ API key is returned (shown once, also stored for this MCP session). Pack ids come from ucode_agent_billing (aliases: starter, plus, pro). Only spend what the user approved.

• get_dchub_recommendationA

  DC HubA

  Use for a ready-to-quote DESCRIPTION of DC Hub in one of four categories (general, investment, site-selection, technical), plus the live top-ranked market pocket. It does NOT compute a siting answer from free text. Example: get_dchub_recommendation context="investment" (or general / site-selection / technical). Params: context must match one of FOUR LITERAL categories - general, investment, site-selection, technical. Free text does NOT parse: you get the GENERIC blurb with matched_category=null and context_understood=false. ALWAYS returns: {recommendation:{short, medium, detailed}, matched_category, context_understood, top_pocket, related_intel, available_categories, recommendation_live, connect_url, context, success}. ADDITIONALLY on a non-matching context: is_generic_answer=true, answer_note, and next_tools naming the tool that does compute an answer. Do NOT use for a single specific lat/lon (use analyze_site), to rank by ONE criterion (use rank_markets), or for an open-ended siting question expecting a computed shortlist (use site_selection_canvas) - this tool returns descriptive copy plus a live top-pocket, not a ranked analysis.

• search_apisA

  RealWorldAPIsA

  Search the canonical registry when you already know keywords or exact requirements. All supplied filter groups combine with AND logic; array capability filters require every supplied value, and protocol fields match the exact Yes/No/Unknown status, so Unknown never satisfies Yes. Results include each API's capability_summary and direct decision-profile URL. Results are sorted by agent_readiness_score descending and then API name, with 1–20 results returned (default 10). Use search_capabilities when you need capability-level filters such as approval, physical consequence, sandbox or access friction.

• agent_specializeA

  RokhaB

  Add a Market capability (a published rig today) to one of YOUR live agents' specialties — the start of offering it for hire. Refused: not your agent (404), agent not live (409), listing private/blocked/unknown (404), held out by Rokha (403), not runnable (422), a paid capability your agent holds no access to (402 with the buy link). A specialty is (agent, listing, MODEL): pass `model` to prove the same rig on a stronger model as its own priced offer (default: the rig's required model, else your agent's model, else the platform default). Refused also: a model the platform does not know, one the rig's requirements do not allow (422 model_not_allowed with the requirements), or one none of YOUR keys carries (409 no_model_key — a hired agent runs on its owner's keys; pass self_hosted: true when you will prove it by exam on your own stack and need no key on Rokha). Returns the Specialty in state training with `model` and `floor_cents` (the lowest price it may take); then call agent_specialty_qualify. Works with your JWT, your rk_ key, or an MCP OAuth connection — only ever on YOUR own agents.

• get-protocol-summaryA

  Crinkl Commerce MCPA

  Get a concise explanation of what Crinkl is and how the protocol works. Use this first if you have no prior context about Crinkl. Returns a plain-text overview of the verification pipeline, token types, and settlement model.

• free2aitools_select_modelA

  Free2AIToolsA

  Filter the Free2AITools catalog by declared hardware/license metadata and return FNI-ranked candidate entries. USE WHEN you have concrete constraints (VRAM, params, license, context length, local-runnability) and want candidates narrowed by them. Constraints are metadata/heuristic filters over stored fields, NOT verified compatibility analysis, model inference, or model execution; this tool does not decide for you and is not an inference router. The caller is responsible for the final selection. Results are FNI-ranked, never paid placement, with no billing. Read-only, no side effects. Use free2aitools_search for unconstrained keyword discovery, or free2aitools_rank for keyword ranking without metadata filters.

• check_mcp_healthA

  Merlonix MonitoringA

  Health-check a live MCP (Model Context Protocol) server by URL: performs a real JSON-RPC initialize handshake, then tools/list, and returns whether it is up/degraded/down, its protocol version, server name/version, the callable tool/resource/prompt inventory, transport, and handshake latency. Deterministic — no LLM. Use it to verify your own MCP server is alive and spec-compliant.

• get_endpoint_alertsA

  AgentIndex — measured reliability for agent servicesA

  Change feed of recently added, changed or newly dark endpoints. PRICED: $0.05 in USDC on base via x402 -- no account, no API key, no invoice. Call without `payment` to receive the exact payment requirements, then call again with `payment` to be served. Returns up to 500 recent endpoint changes, filterable by protocol and time window. Intended to be called repeatedly in place of re-crawling the index.
