Paste this into Muse: "Use Niche Editorial Intelligence to help me. It is a free service with an MCP server at https://api.nicheangle.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer. Tools: - niche_signal_scan: Niche (nicheangle.com) story discovery: find stories worth writing about, then draft and publish platform-native social content (LinkedIn, X threads, Instagram, newsletter) from them. This is story discovery, not content generation: Niche reads primary sources, separates signal f - niche_draft_direct: Draft the creator's own take or product straight into posts, with no research scan and no story/angle picks. Use this for product-led or bring-your-own-content work: a specific thing to say ('new walnut dining table, live edge, $2,800') or a page to repurpose. The signal pipeline - niche_intelligence_query: Niche (nicheangle.com) research and analysis: answer an analyst-shaped question over fresh-scanned sources and get an intelligence answer as the deliverable, not a single post. Use for: 'the 10 biggest developments in X this week', 'what's emerging before it goes mainstream', 'wh - niche_session_state: Universal poll endpoint: read the full current state of a session. Returns status, ranked stories, picked story_id, generated angles, picked angle_id, draft outputs (with trust fields), and an elicitation hint for whatever decision is next. Call this whenever you need to check pr - niche_angle_propose: Niche content angles: pick a story from the discovery slate and surface the strongest angles worth publishing, the editorial-judgment step that turns a development into a piece. Returns five angles[], each with frame, hook, tension, cta_direction, and cta_variants (a swap palette - niche_draft_create: Niche draft content: lock the chosen angle and turn it into platform-native social drafts (LinkedIn post, X thread, Instagram, newsletter/long-form), ready to review and publish, the downstream payoff once the story and angle are decided. Returns immediately with status=cp3_gener - niche_draft_revise: Applies the values you pass to a specific output. Accepts any subset of the output's fields: caption, hashtags, or partial script updates (hook / body / cta / hook_tweet / body_tweets / title / subtitle / pull_quote / cover_slide / slides / cta_slide / alt_text / card_headline, w - niche_draft_publish: Publish a single output to its platform. Defaults to dry_run=true: returns the would-publish payload plus any verifier blocks without actually filing. Set dry_run=false and provide an idempotency_key to commit. The commit is the only irreversible action in the workflow; the agent - niche_brand_profile_set: Set or update the persisted brand profile for a brand. The profile is a structured JSON document applied across every pipeline stage: voice rules, banned terms, canonical vocabulary, framing allowlist, channel config, compliance disclosures, and verifier overrides. Use it to pers - niche_list_sessions: Enumerate the user's recent sessions. Returns id, niche_input, status, `outcome`, target_platforms, picked story/angle ids, and created/updated_at for each. Use this when the session_id has been lost (across agent invocations, hours of work, etc.) or to find an in-flight session - niche_brand_kit_ingest: Auto-populate the user's BrandKit (palette / fonts / tagline / logo / wordmark / boilerplate / voice notes) from files, a URL, or pasted text. Additive by default: fills empty fields, leaves populated ones alone. Idempotent: re-running the same inputs doesn't double-write. Overwr - niche_brand_kit_ingest_status: Poll the result of an async niche_brand_kit_ingest. Pass the `ingest_id` it returned. status: 'ingesting' (keep polling) | 'done' (response carries the full kit plus detected[]/skipped[]/errors[]/diff[]/left_unchanged_because_populated[]) | 'failed' (error plus failed_step; the k - niche_voice_profile_ingest: Extract voice primitives (register / sentence rhythm / lexicon preferences / punctuation habits) from post-shaped text and persist onto the user's VoiceProfile. The voice primitives thread into content generation so generated copy matches the user's actual writing voice. Two inpu - niche_brand_profile_get: Read back the persisted brand profile without modifying it. Use it to confirm a profile landed as expected, to check the active profile a run is bound to, or to inspect the current shape before a partial update. Pass `brand_id` to read one profile; omit it to list all (brand_id, - niche_brand_kit_guided_setup: Return a structured question chain the agent walks the user through to populate the BrandKit, VoiceProfile, and (optionally) BrandProfile. Each entry carries an `intent` describing what the answer is for (so the agent paraphrases in its own voice based on the conversation it's al - niche_brand_kit_update: Set specific BrandKit fields by name. The write path for the structured fields (tagline / boilerplate / voice_notes / forbidden_phrases / signature_phrases / endcard preferences / video voice preference / colors / fonts) without going through the ingest engine. Use after niche_br - niche_render_image_card: Render a visual onto a post at CP3, or edit an existing image. scope: 'full' (default) renders a new visual and requires `background`. 'recomposite' re-composites new text, color, or size over the retained background at no charge. 'restore' reverts to the prior image from history - niche_render_reel: Render a 9:16 vertical reel for a session at CP3. A per-beat script (typically 4-7 beats) is composited into one video: stills, voiceover, motion, caption overlays, and an endcard (~30-120s). Reels are delivered as a downloadable file for the user to publish. scope: 'full' (defau - niche_session_revert: Revert a session back to an earlier checkpoint. Use when the user (or you) decided the picked story / angle isn't the right one and you want to re-pick without starting a new scan. to='story': cancels current generation, returns to CP1_AWAITING_STORY with the same ranked stories - niche_session_cancel: Cancel a running session. Marks status=failed with an error_message ('cancelled by user' or the caller's reason), and stops the in-flight orchestrator if any. Used when you want to free a slot under the concurrent-session cap without deleting the session (history and audit trail - niche_session_export: Export a session as a structured calendar artifact preserving session_id and per-story story_id traceability. Use after a niche_signal_scan when you want a metadata-rich content backlog instead of running individual pieces end-to-end. Outputs a standard editorial-calendar shape s - niche_add_output: Add an output cell to a session that's already reached CP3. Use this when the user picked a small initial cell set, previewed the drafts, and now wants another surface (e.g. the session started with linkedin:text_post and the user wants to add instagram:carousel too). Text-only c - niche_reuse_asset: Copy an image that already exists on one output onto another cell, instant and free (no regeneration, no credits). Use this when the user wants 'the same image' on a second surface ('use the LinkedIn image on X', 'same picture on the newsletter') instead of niche_render_image_car - niche_attach_image: Upload or attach a user-supplied or externally-designed image (bring-your-own asset) to a post: the creator's own visual (a product shot, their actual work, a card designed elsewhere) instead of an AI-generated image (niche_render_image_card photo, paid) or a flat brand card. Fre - niche_whoami: List the full tool catalog and orient the agent, in one read-only call. Returns every registered tool name and the live tool count, the account (plan and credit balance), a capability map (tools grouped into bands: discover, decide, draft, render, publish, brand, session, plus th Screening checks: - MCP handshake: pass (Answered in 338ms) - Domain against threat feeds (Cloudflare security DNS): pass (api.nicheangle.com, nicheangle.com not flagged) - Published packages against the OSV malicious-package database: n/a (No npm or PyPI package published) - Hidden instructions or invisible characters in tool text: pass (25 tools read, nothing found) - Inputs asking for passwords, card numbers or seed phrases: pass (None found) - Domain and redirects: pass (Domain registered 162 days ago) - AI review of purpose and tool behavior: pass (No concerns)
