"A tool for inspecting and debugging Model Context Protocol (MCP) servers" matching MCP tools:

• defi_protocolsA

  MCPFax Macro & Market IntelligenceA

  Rank DeFi protocols by total value locked from DefiLlama, filtered by chain, category or name substring, with each protocol's slug, category, chain list, TVL in USD, 1d/7d TVL change and market cap. Use it to size a protocol, find the biggest venues on a chain, or resolve the slug the protocol-detail tool needs. A protocol DefiLlama publishes no TVL for keeps a null figure, never a zero. Read live at request time and held for 5 minutes. Costs $0.008 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /defi/protocols.

• get_price_estimateA

  BridgeNode MCPA

  Estimate the USDC cost of a chat completion request before paying — free, no payment, no authentication required. Read-only: no state changes and no external calls; the estimate is computed locally from server pricing config, so repeated calls with identical inputs return identical results (idempotent). Use this tool to check the exact price for a given model/mode, messages, and max_tokens before calling the paid chat_completions tool. Provide either mode (auto/eco/premium routing) or model (explicit id, mutually exclusive with mode); one of the two is required — if both are sent, model wins. mode values: auto = cheapest model fitting the context, eco = cheapest available, premium = best model.

• 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.

• siteborne_get_service_healthA

  SITEBORNE Utility NetworkA

  Report MCP server readiness and production-enable status for each SITEBORNE service. Use when: an agent must check protocol availability, tool count, or whether a service is currently production-enabled before selecting a paid tool. Do not use when: a quote is needed (use siteborne_get_quote) or company, web, document, or agent-output evidence work is required (use the corresponding SITEBORNE service tool). Behavior: read-only and credential-independent; it does not perform paid evidence work, create quotes, verify payment, call providers, write service state, create Workflows, or settle. Economics: free of charge; it never issues a payment challenge. Failure: it depends on no provider, so it does not fail because a provider is unavailable. Returns: the server and protocol versions plus truthful local, production, and external-publication status for all four evidence services.

• query_eventsA

  TracklutionA

  Note: this tool holds data for a limited timeframe — only the last ~7-14 days are available, depending on the container. Paginated list of raw events for a date range, with filters (event_name, source, status, and 10 has_* click-ID presence flags). DATA RETENTION: the v2 store currently holds only the last ~7-14 days. Older date_from values pass validation but return empty rows. A "warnings" array is added when date_from is outside the retention window. USE WHEN: - User wants to loop through all events for a given date range, inspecting data from each one in detail. - User wants to enumerate events matching a filter (e.g. "show all Purchase events with gclid this week", "list error events from yesterday"). - User explicitly wants raw event records, not aggregates. DON'T USE for counts, totals, top-N rankings, breakdowns by source/day — use get_report (orders of magnitude faster on aggregates). For a single event by ID, use list_events. STATUS FILTER: defaults to "processed" — these are the real, successfully-recorded events that nearly every analytics question is about. Only set status explicitly when debugging delivery/ingestion issues: "pending" (queued, not yet processed), "error" (processing failed), "rejected" (validation/spam blocked). Asking for non-processed events without a debugging reason will mislead the user. Pagination is cursor-based: pass the returned meta.cursor.next_cursor back as cursor on the next call. Stop when has_more is false. Backend caps date range at 30 days.

• dune_queryA

  AgentPay — trust routing + spend caps for x402 agentsA

  Run any Dune Analytics query and return live onchain results by query ID. Use fast_only=True for live bots — returns cached result instantly or raises immediately, never blocks. Use when: You need deep onchain analytics from a specific Dune query — protocol revenue, user counts, custom metrics. Not for: you have no Dune query ID — the other tools cover prices, derivatives, TVL and security without one; you need sub-second answers — set fast_only=true or use a cached tool. Returns: rows[], columns[], row_count, generated_at from the Dune Analytics query result Example response: {"query_id":3810512,"row_count":2,"columns":["protocol","revenue_usd"],"rows":[{"protocol":"Uniswap V3","revenue_usd":1243800},{"protocol":"Aave V3","revenue_usd":987200}],"generated_at":"2026-03-22T00:00:00Z","source":"dune"} Price: $0.000 USDC per call

• submit_conversation_feedbackA

  Agent CentralA

  Submit a concise, redacted, task-specific product issue to agentcentral only after the user explicitly asks to send feedback and confirms the packet. Include only the minimum redacted evidence needed to investigate. Do not request or submit conversation history, prior-turn arrays, or raw transcripts. Do not submit API keys, bearer tokens, Connector URLs, refresh tokens, buyer names, addresses, phone numbers, emails, order IDs, tracking IDs, gift messages, full tool payloads, or unrestricted seller metrics. Free-text ASINs are aliased automatically; use related_asins only when specific ASINs are necessary for debugging. This creates a product feedback item for human review, not a support ticket and not model training data.

• get_transaction_infoA

  blockscout-mcp-serverA

  Get comprehensive transaction information. Unlike standard eth_getTransactionByHash, this tool returns enriched data including decoded input parameters, detailed token transfers with token metadata, transaction fee breakdown (priority fees, burnt fees) and categorized transaction types. By default, the raw transaction input is omitted if a decoded version is available to save context; request it with `include_raw_input=True` only when you truly need the raw hex data. Essential for transaction analysis, debugging smart contract interactions, tracking DeFi operations.

• 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.

• colour_mixA

  Colour MemoryA

  Simulate perceptually modelled subtractive mixing of two colours in CIE Lab space (not RGB screen blending). Returns the resulting mixed hex value and its nearest archive match with cultural context. Uses CIE Lab subtractive model for perceptual accuracy. Example: mixing Prussian Blue and Yellow Ochre gives a muted green — the tool identifies which archive colour that green most closely matches.

• 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

• demand.list_verticalsA

  iwant.fyi - shop, price-check and keep lookingA

  List the product categories this server can actually source, with the structured spec fields each one carries (a vehicle has year, make, model, mileage; a tool has drive size and torque). Call it before a first search to learn which `vertical` values are accepted, or when a search returns nothing and you need to check the category is covered at all. Free, instant, no side effects. Protocol v1.0 §8.2.

• read_docsA

  clipkitA

  Return a canonical Clipkit doc as text. topic "card" = the ~8KB compact authoring card — the recommended context for authoring; "pattern-lighting" = the shine/neon/glow technique rigs; "pattern-data-viz" / "pattern-cinematic-ui" / "pattern-ui-screencast" / "pattern-promo-teaser" = ~4-5KB pattern cards (proven idioms: count-ups and bar rows; product hero shots with camera rigs; faked app UI with typing/cursor/clicks) — load ONE alongside the card when the brief matches its archetype; "agents" = the full authoring guide (fetch only when the card doesn't cover a need); "protocol" = the formal field spec; "brand" = brand reference. (Same docs offered as MCP resources, exposed as a tool so you can read them directly — resources are not always model-readable.)

• mcp_searchA

  Find MCP - Agentage MCP DirectoryA

  Search the agentage MCP directory - a public catalog of Model Context Protocol servers crawled from the official registry - for servers matching a keyword, optionally narrowed by type, category, language, or license. Use this FIRST whenever the user wants to discover, find, compare, or pick an MCP server ("is there an MCP for X", "which MCP servers do Y"). Results are ranked by text relevance to the query first, then by popularity, so the best match is on top. Returns a page of lean cards (slug, title, description, category, transport, match_score - text relevance the ranking is based on, details_url). To read one server's full packages, tools, and install command, call mcp_get with the slug from a result; open a card's details_url for the human detail page. Valid category, language, and license values come from the mcp_categories tool, not from guesswork - call it before filtering and pass its labels verbatim, or the call is rejected. Read-only - never installs or runs anything.

• models_listA

  HubrisA

  Walk the whole Hubris catalogue page by page, ordered by model id. Returns every active model with its capabilities, context window and ruble price. Use this when you need the complete catalogue — to cache it, to count models, or to scan for something no filter covers. When you are looking for a model that fits a task, use models_search instead: it filters by capability, price and context server-side and saves you a few hundred rows. Paging: read `nextCursor` from the response and pass it back as `cursor`. When `nextCursor` is absent you have reached the end. The catalogue holds roughly 550 models, so a full walk is about 11 calls at the default page size.

• 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.
