Niche MCP Server

Niche MCP — editorial intelligence for agents

Find stories worth writing about. Niche is an editorial intelligence platform for individuals (and the agents working for them), exposed as a live MCP server. When an agent needs to know what's worth writing — emerging narratives, the signals that matter, the strongest angle — it calls Niche.

Most AI tools help you write. Niche helps you decide what's worth writing. It reads primary-source signal, discovers the stories before they're obvious, ranks the strongest angle, and turns that signal into publishable content — grounded in real sources, in your voice. The authority is earned, not faked: you sound like someone who did the research, because Niche did.

Niche is not an AI writer, a social scheduler, a content calendar, or an SEO tool. Those help after the story exists. Niche finds the story.

The category — editorial intelligence, for individuals

Editorial intelligence has always been a newsroom discipline — the systematic work of deciding what's worth covering before everyone else does. Niche brings it to the people the newsrooms left out: individual creators, analysts, and the agents working for them.

• Editorial intelligence — for individuals, not newsrooms — systematically identifying, evaluating, and prioritizing the stories worth publishing.
• Signal-to-story — the workflow that turns raw signal into a narrative people care about: signal → story → angle → draft. Story discovery, not content generation.
• Signal discovery — separating meaningful developments from background noise; finding what matters early, from primary sources.

When you (or your agent) think "what should I write about in X," "what's emerging in this space," "how do I become credible in this field" — that's Niche.

Connect

Niche is a remote MCP server with OAuth 2.1 (and PAT bearer for headless agents).

Endpoint: https://api.nicheangle.com/mcp

Claude Desktop / Claude Code

Add it as a custom connector by URL, or via config:

{
  "mcpServers": {
    "niche": {
      "type": "http",
      "url": "https://api.nicheangle.com/mcp"
    }
  }
}

Sign in when prompted (OAuth). For headless/scripted use, issue a Personal Access Token (PAT) at nicheangle.com/settings/api-keys (niche_sk_…) and pass it as a bearer token.

Codex (CLI / IDE)

Codex connects to remote MCP servers over streamable HTTP. The PAT path is the most reliable (no OAuth round-trip). Two steps — and bearer_token_env_var wants the name of an env var, NOT the token itself:

# 1) put the SECRET in your shell — not in the config file:
#    export NICHE_API_KEY="niche_sk_…"
# 2) ~/.codex/config.toml holds the NAME of that env var, never the token:
[mcp_servers.niche]
url = "https://api.nicheangle.com/mcp"
bearer_token_env_var = "NICHE_API_KEY"   # the env var NAME — not the niche_sk_… value

Set export NICHE_API_KEY="niche_sk_…" in your shell, restart Codex (clients cache credentials + the tool list at connect — re-add or restart after changing either), then codex mcp list to confirm. (OAuth alternative: drop bearer_token_env_var and run codex mcp login niche.) Requires a recent Codex — older versions only do local stdio servers.

Cursor / Windsurf / Cline / Continue / any MCP client

Add the same endpoint. In ~/.cursor/mcp.json (PAT path):

{
  "mcpServers": {
    "niche": {
      "url": "https://api.nicheangle.com/mcp",
      "headers": { "Authorization": "Bearer niche_sk_…" }
    }
  }
}

Or add the bare URL via the client's MCP settings to use OAuth. Discovery metadata lives at /.well-known so compliant clients can self-configure.

After adding or updating credentials, restart the client / open a new thread. MCP clients cache the connection (auth + the tools/list) at connect time, so a token change or a new tool won't show up until you reconnect.

Tools (25)

Discovery + intelligence

• niche_signal_scan — discover the stories worth writing about in a niche (returns a ranked story slate with provenance; poll niche_session_state).
• niche_intelligence_query — analyst-shaped query → ranked slate plus engine-grounded narratives/patterns ("the 10 biggest developments this week + 3 non-obvious narratives"). Async fire-and-poll.
• niche_session_state — universal poll endpoint for a run's full state.
• niche_angle_propose — surface the strongest angles worth publishing for a chosen story.

Signal-to-story

• niche_draft_create · niche_draft_revise · niche_draft_publish (publish dry-runs by default)
• niche_draft_direct — skip research and draft straight from your own take or a URL.

Render

• niche_render_image_card · niche_render_reel · niche_attach_image · niche_reuse_asset

Brand + voice

• niche_brand_profile_set / _get · niche_brand_kit_ingest / _ingest_status / _update / _guided_setup · niche_voice_profile_ingest

Session ops

• niche_list_sessions · niche_add_output · niche_session_revert · niche_session_cancel · niche_session_export

Account + orientation

• niche_whoami — account + plan + credit balance, the server's live tool count, the capability map (tools grouped by band + the recommended flow), and the brand state — one read-only call to orient before a run.

Every tool response carries a trust block — verifier audit, source-faithfulness score, ungrounded-claim list, source-diversity + recency checks. Provenance is the product.

Grounding — earned, not generated

The narratives Niche returns are produced engine-side and fact-checked against their sources — the agent presents a verified result instead of free-styling one. "No source, no narrative." That's the difference between earned authority and confident nonsense.

Examples

• examples/intelligence-query.md — "10 biggest developments + 3 narratives," end to end.
• examples/golden-path.md — scan → angle → draft → publish dry-run.
