• research_nicheA

  KDP Niche ResearchA

  Get detailed KDP niche intelligence for a specific keyword. Returns demand score, competition score, Amazon BSR range, estimated monthly revenue, review threshold, average book pricing, and data freshness for the given Kindle publishing niche. Pricing tiers (x402 USDC on Base network): - $0.03 per query for cached/pre-seeded keywords - $0.10 per query for live on-demand research (new keywords) Use the free `list_niches` tool first to see available keywords. Payment options: 1. Set the KDP_X_PAYMENT environment variable on the server for auto-pay. 2. Pass a valid x402 payment header via the x_payment argument. 3. If neither is set, the tool returns structured 402 payment instructions that an x402-capable agent can use to construct and retry payment. Args: keyword: The KDP niche keyword to research (e.g. "romance novels", "keto cookbook") x_payment: Optional base64-encoded x402 payment header. Takes precedence over the KDP_X_PAYMENT environment variable.

• gutenberg_get_textA

  gutenberg-mcp-serverA

  Retrieve the plain-text content of a Project Gutenberg book, stripped of the standard license header and footer so the response contains only the literary work. For long works — novels routinely run 500KB–2MB — use offset and limit to read in chunks rather than fetching the whole book at once. The response reports totalChars and remainingChars for reliable pagination. Prefers UTF-8 plain text; falls back to an HTML edition converted to text; refuses audio books (media_type "Sound") with a clear error.

• newsA

  NewsMCPA

  Search already-synthesized news events — pre-built story digests — or fetch one by id. Each story comes with a generated headline, one-liner, abstract, key actors, and industry/event-type labels. Use it for a quick digest of what happened, for deal/incident-type or industry filtering, and for corroboration ranking. Nothing is required: a bare call returns the most-corroborated stories of the last 24 hours. Limits — keyless: 7-day `from_` lookback, 20 calls/hour, 20 stories per call, over-limit narrowed with a notice. With a key: per-plan ceilings (free tier today 14 days, 50 calls/hour, 50 stories), over-limit rejected rather than narrowed. Call `check_limits` for the live numbers; it is free and never spends the budget it reports on. Filters combine with AND; `event_type`, `content_type`, and `sector` each accept several comma-separated values combined with OR.

• check_textA

  WSC - Writing Style CheckerA

  Analyze text for writing style issues: weasel words, passive voice, duplicate words, long sentences, nominalizations, hedging, filler adverbs, and research-cited AI tells. Read-only and stateless — text is analyzed in memory on the hosted server and never stored. Returns a plain-text report with each issue's line and column, the matched text, surrounding context, and the reason for AI tells; texts over 100,000 characters return an error message. This hosted server has no filesystem access — the wsc-mcp npm package adds a check_file tool for local files. It only reports issues — to auto-remove duplicate words, follow up with fix_duplicates.

• adcritter_get_platform_overviewA

  AdCritter for BuildersA

  Start here. Returns the AdCritter platform overview - what AdCritter is, the entity hierarchy (organization > advertiser > campaign > ad), the happy path for getting ads running, and how to navigate the other MCP tools. Applications built from this guidance are REST API clients that call /v1/ endpoints, not MCP tool callers. Before writing code, call adcritter_get_api_reference(entity, action) for each entity and action you plan to use - tool descriptions and parameter names describe conceptual behavior only, and do not match actual API routes, field names, query parameters, or response shapes.

• trending_stories_toolA

  SantimentA

  Fetch current trending crypto stories with sentiment analysis ## When to use vs `combined_trends_tool` Prefer this tool when only stories are needed: it is the cheap, fast path and has no per-tool rate-limit sub-cap. `combined_trends_tool` is a superset — same stories plus trending words, their context and AI-generated bull/bear summaries — but it calls an LLM, so it is slower and capped much lower per plan. Use it only when trending *words* or those summaries are actually needed, and never call both for the same question. ## Parameters - `time_period` - Time period for trending stories (e.g., '1h', '6h', '1d', '7d'). Defaults to '1h' (last hour). - `size` - Number of trending stories to return (max 10). Defaults to 10. ## Response - `trending_stories` - List of trending stories. - `time_period` - Time period for trending stories. - `size` - Number of trending stories to return. - `period_start` - Start time of the time period. - `period_end` - End time of the time period. - `total_time_periods` - Total number of time periods. ## Trending stories - `title` - Title of the story. - `summary` - Summary of the story. - `bearish_sentiment_ratio` - Bearish sentiment ratio. - `bullish_sentiment_ratio` - Bullish sentiment ratio. - `score` - Score of the story. - `query` - Query used to find the story. - `related_tokens` - List of related tokens. They have the format `BTC_bitcoin` - first part is the ticker, second part is the slug in Sanbase.

  Moltline Humanizer — Voice-Matching EditorA

  Build a measurable voice profile from samples of a person's real writing. FREE. Feed it 2+ samples (emails, posts, essays — 150+ words total) and use the result with humanize_plan / verify_rewrite. Typical input {"samples": ["<email text>", "<blog post>"]} returns {"label": "my-voice", "target_metrics": {"avg_sentence_len": ..., "burstiness": ..., ...}, "favorite_words": [...], "signature_habits": ["..."], "words_analyzed": N}. Use on samples the person actually wrote, to build a target profile. Not for scoring an unknown draft (ai_tell_scan) and not on text the person did not write. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"} (for example {"error": "need 150+ words of real writing across the samples"}). Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

• show_roomsA

  Roomza Hotel IntelligenceA

  REQUIRED whenever you present rooms. Whenever you are about to mention, recommend, or describe one or more specific rooms to the user, you MUST call this tool with those room UUIDs INSTEAD of writing the rooms in text. This is mandatory even when there is only ONE matching room — show it as a single hero card, never describe a lone room in prose. Call this BEFORE writing any prose about the rooms; the cards must appear first, then a brief summary. Pass room UUIDs (from get_hotel_rooms or search results) in ranked order, best first, 1 to 8 rooms. ALWAYS pass check_in and check_out when you know the user's dates: card prices are then for those exact dates. Without dates, cards show a typical from-price that can differ a lot from any specific dates. Each card shows photo, Roomza score, view, bed, and price. NEVER ask the user whether they want to see cards or images — just call this tool.

  UI VerifyA

  Page through one build's stories filtered by status (resolved by commitSha/prNumber/buildId). Use it to read past get_build's first page, or to browse the unchanged/passed stories get_build only counts. status='changed' returns changed stories (same shape + order as get_build, regression-first, each with its comments {total, unresolved}; unresolved>0 means an open review note - read it with list_comments first); status='failed' returns failed stories; status='unchanged' returns the stories that did NOT change this build but have a baseline on this branch (storyId, viewport, browser) - fetch any of their images by storyId with get_diff or render_diff_image to confirm 'identical to baseline'. Returns { stories, nextCursor }: pass nextCursor back as `cursor` for the next page; null means no more. limit defaults to 25 (max 100). Unchanged is only available once the build has settled (an in-progress build has rendered nothing, so it returns an empty page).

• call_write_toolA

  Opus Growth, Ad Platforms MCP ConnectorA

  Run a WRITING Opus tool by name (create / update / pause / remove) — the gateway to every write capability that is not in your visible core set. Use search_tools(query) FIRST to get the exact name and its argument schema, then call it here. name = exact tool name; arguments = that tool's parameters as an object. Writes go to the advertising platform APIs the user has connected (Google Ads, Microsoft Advertising, Meta, TikTok, LinkedIn) and to Opus Growth's own hosting/WordPress services. Read-only tools are refused here — use call_tool for those. The tool's own preview-and-confirm gate still applies: tools that change a live account return a PREVIEW with confirm=false and only apply with confirm=true. Credits and access rules behave exactly as calling the tool directly.

• gunspec_api_operationA

  GunSpecA

  Returns what the GunSpec API reference documents for an endpoint: its parameters and accepted values, the plan it needs, whether a key is required, caching, every error status with the error.reason values to branch on, and the languages a sample is printed in. Use this tool before writing or explaining code that calls the GunSpec API, instead of recalling parameters. The path may be a template (/v1/firearms/{id}), a concrete path or a URL; a partial path such as /v1/vendor lists the operations under it.

• combined_trends_toolA

  SantimentA

  Combined trends tool that fetches trending words, stories, and documents in parallel. This tool provides a unified view of all trending data - words with their documents and stories - in a single response across all crypto projects. ## When to use vs `trending_stories_tool` This is a superset of `trending_stories_tool`: same stories, plus trending words, their context and AI-generated bull/bear summaries. It calls an LLM, so it is slower and has a tighter per-tool rate-limit sub-cap than every other tool.

Do not call both tools for the same question. ## Parameters - `time_period` - Time period for trending data (e.g., '1h', '6h', '1d', '7d'). Defaults to '1h' (last hour). - `size` - Number of items per category to return (max 30). Defaults to 10. - `include_stories` - Include trending stories in response. Defaults to true. - `include_words` - Include trending words in response. Defaults to true. ## Response - `trends` - Combined trending data containing stories and words. - `metadata` - Request metadata including time period, size, and included data types. - `errors` - Any non-fatal errors encountered during data fetching. ## Trending Data Structure ### Stories - `title` - Title of the trending story. - `summary` - Summary of the story. - `score` - Trending score. - `query` - Search query used to find the story. - `related_tokens` - List of related crypto tokens (format: "BTC_bitcoin"). - `bullish_sentiment_ratio` - Bullish sentiment ratio. - `bearish_sentiment_ratio` - Bearish sentiment ratio. ### Words - `word` - The trending word. - `score` - Trending score. - `slug` - Associated project slug (if word is project-related). - `summary` - AI-generated summary of discussions. - `bullish_summary` - Summary of bullish sentiment. - `bearish_summary` - Summary of bearish sentiment. - `positive_sentiment_ratio` - Positive sentiment ratio. - `negative_sentiment_ratio` - Negative sentiment ratio. - `neutral_sentiment_ratio` - Neutral sentiment ratio. - `positive_bb_sentiment_ratio` - Positive bull/bear sentiment ratio. - `negative_bb_sentiment_ratio` - Negative bull/bear sentiment ratio. - `neutral_bb_sentiment_ratio` - Neutral bull/bear sentiment ratio. - `context` - Related words that appear with this trending word. - `documents_summary` - AI-generated summary of related social media discussions.

• get_instagram_user_highlight_detailA

  AIsa SocialA

  Returns the stories inside one highlight album: reel_type, latest_reel_media, the owning user, and items, each a raw Instagram story media object. Pass the bare numeric id from get_instagram_user_highlights. The response echoes that id back in the prefixed form highlight:<id>, and feeding the prefixed form to this endpoint returns 404 with a message blaming deletion or a private account, which points at the wrong cause; send the bare number. Measured at 630 KB for an album of 38 stories, so size scales with the album.
