NewsBlog Composer MCP
# NewsBlog Composer MCP
**A research and audit tool for people who write.** It finds corroborated
stories, pulls out facts with their sources attached, mines keywords from that
reporting, hands the writer a brief, reviews the draft they wrote, and builds the
schema, banner prompt and publishing pack around it.
**It does not write the prose, on purpose.** A model writing the sentences is
exactly what an AI detector catches, and no amount of cliché-removal changes
that: detectors measure how predictable the wording is, not how many stock
phrases it contains. More to the point, the byline claims a person wrote it.
So the split is: the server does search, verification, extraction, keywords,
structure, schema and auditing. The person writes the sentences. `draft_brief`
gives them everything to start with; `review_draft` tells them where the draft is
weak without rewriting a word.
**It runs with zero API keys.** Every credential is an upgrade, not a
requirement. See [No keys? Start here](#no-keys-start-here).

## Install
Windows:
```powershell
git clone https://github.com/Mohammed-Jameal-J/newsblog-composer-mcp.git
cd newsblog-composer-mcp
py -m venv .venv
.venv\Scripts\activate
pip install -e .
copy .env.example .env # optional: every value in it is optional too
```
macOS / Linux:
```bash
git clone https://github.com/Mohammed-Jameal-J/newsblog-composer-mcp.git
cd newsblog-composer-mcp
python3 -m venv .venv
source .venv/bin/activate
pip install -e .
cp .env.example .env # optional: every value in it is optional too
```
Check what it can do on your machine:
```powershell
python -m newsblog_mcp.diagnose "your test headline here"
```
That prints which providers are configured, which will be tried, and the result
of a live `verify_news` call. Run it before wiring the server into a client —
if search is blocked by a corporate proxy or VPN, this is where you find out.
Offline test suite (no network needed):
```powershell
python tests\smoke_test.py
```
## Connect it
**Claude Desktop** — `%APPDATA%\Claude\claude_desktop_config.json`:
```json
{
"mcpServers": {
"newsblog": {
"command": "C:\\path\\to\\newsblog-composer-mcp\\.venv\\Scripts\\python.exe",
"args": ["-m", "newsblog_mcp.server"]
}
}
}
```
On macOS the file is `~/Library/Application Support/Claude/claude_desktop_config.json`
and the command is `/path/to/newsblog-composer-mcp/.venv/bin/python`.
**Claude Code** — `.mcp.json` in your project:
```json
{
"mcpServers": {
"newsblog": {
"command": ".venv/Scripts/python.exe",
"args": ["-m", "newsblog_mcp.server"]
}
}
}
```
Any other MCP client: launch `python -m newsblog_mcp.server` over stdio.
---
## Publishing and connecting
**Claude Desktop / Claude Code** run it over stdio, which is what the install
section above sets up.
**ChatGPT cannot spawn a local process**, so stdio will never reach it. Run the
same server over HTTP and deploy it behind HTTPS:
```powershell
newsblog-composer-mcp --http --host 0.0.0.0 --port 8000
```
Then in ChatGPT: Settings → Connectors → Advanced → Developer mode, then **Add
custom connector** pointing at `https://your-host/mcp`. Custom connectors need a
Pro, Team, Enterprise or Edu plan.
**Publishing to the MCP Registry** needs the package on PyPI first, then the
`mcp-publisher` CLI with `server.json` in this repo. The `name` field must match
your GitHub username: `io.github.<username>/newsblog-composer`.
## How to test it
Three levels, cheapest first.
**1. Offline, no network — proves the logic.**
```powershell
python tests\smoke_test.py
```
85 checks covering schema parity, the SEO audit, AI-word detection, publisher
identity behind aggregator links, clustering, and the publishing pack. All should
pass in about two seconds.
**2. Network — proves search reaches you.**
```powershell
python -m newsblog_mcp.diagnose "a headline you saw in the news today"
```
One line per provider with timings, then the verdict. What you want to see is
`independent_publishers` naming several real outlets and `reference_candidates`
holding real publisher URLs.
**3. A whole post, end to end.**
```powershell
python examples\build_today_example.py
```
Builds a complete package from a real story using facts already in the file, and
prints the keywords, schema validation, AI-word check, human score and SEO score
before writing the output folder. Use it as the reference for what a good run
looks like. `examples\build_mistral_example.py` does the same for the
hand-written reference post.
**4. In Claude Desktop**, after restarting it:
> Use find_stories to get today's AI stories, pick the best corroborated one, and
> build the full blog package. Run find_ai_words until it comes back clean, then
> give me the publishing pack and the paste file.
## The tools
| Tool | What it does | Needs a key? |
|---|---|---|
| `capabilities` | Reports which providers are live and which fallbacks are in use | no |
| `find_stories` | Turns a topic into today's actual stories, grouped and ranked by corroboration and freshness | no |
| `verify_news` | Searches news providers, keeps matching results, counts independent publishers | no (keyless RSS) |
| `fetch_article_facts` | Downloads sources, extracts facts, short attributed quotes and figures | never |
| `draft_brief` | Hands the writer the structure, sourced facts, keywords and FAQ candidates | never |
| `review_draft` | Reads the writer's draft and says where it is weak. Rewrites nothing | never |
| `humanize_text` | Optional rewrite pass. Prefer `review_draft` | optional |
| `find_ai_words` | Finds every stock AI phrase with the sentence it sits in | never |
| `score_ai_text` | 0–100 human-readability score | optional |
| `generate_image` | Concept banner, trademark filter applied first | no (watermarked) |
| `seo_keywords` | Mines keywords from the fetched sources; long-tail and FAQ queries from Google autocomplete | no |
| `seo_audit` | Scores the finished body against on-page rules, returns fixes | never |
| `build_publishing_pack` | Title, labels, permalink, alt text and a paste-ready Gemini image prompt | never |
| `build_schema` | Renders HTML body + both JSON-LD blocks, then validates them | never |
| `save_and_present` | Writes the package to `output/`, with canonical/OG/Twitter tags | never |
Resources: `newsblog://house-style` (structure and sourcing rules for the
drafting step) and `newsblog://humanizer-rules` (the rewrite rule set).
## The flow
There are two entry points, depending on what you type.
**A topic** — "today's AI news", "electric vehicles", "Indian fintech". There is
no claim to verify yet, so start by finding out what happened:
```
find_stories("AI", days=1)
↓ stories grouped by event, ranked by publisher count then freshness
pick one from ready_to_write, check its age_hours
verify_news(story.headline)
↓ … and continue as below
```
**A specific headline** — start at `verify_news` directly. Note that an old
headline correctly returns old sources; `days` limits how far back to look.
```
verify_news(title)
↓ stop here if is_legit is false
fetch_article_facts(result.fetchable_urls) # or story.fetchable_urls
↓
seo_keywords(title, [fact.text for fact in facts])
↓ primary + secondary keywords, slug, meta title/description,
and FAQ questions taken from real autocomplete data
draft_brief(headline, facts, keywords)
↓ the writer writes the draft themselves
review_draft(draft, facts) → must_fix / worth_fixing / consider
↓ the writer revises; repeat until must_fix is empty
find_ai_words(draft) → until `clean` is true
↓
build_publishing_pack(...) → title, labels, permalink, Gemini image prompt
paste the prompt into Gemini, upload the image, take the public URL
↓
build_schema(article, faq, image, references, keywords)
↓ fix anything in validation.issues, then call again
seo_audit(html_body, primary_keyword, ...)
↓ fix everything in must_fix, then call again
save_and_present(..., meta=schema.meta, pack=pack)
```
Output lands in a timestamped folder under `output/`:
| File | What it is |
|---|---|
| `publish-pack.md` | Title, labels, custom permalink, search description, alt text, Gemini image prompt |
| `paste-into-blogger.html` | Both JSON-LD blocks then the styled body — the file you paste |
| `report.md` | Verification verdict, human score, AI-word status, SEO score, references |
| `index.html` | Standalone preview with meta, canonical, OG and Twitter tags |
| `body.html`, `*.jsonld`, `meta.json` | The pieces, separately |
Three guardrails are enforced in code, not left to the model:
- `verify_news` returns `is_legit: false` unless at least two independent
publishers match the headline, or one primary/official source does.
- `build_schema` returns `validation.issues` listing every mismatch: an FAQ
question that differs between the HTML and the FAQPage schema, an image URL
that differs between the `<img>` tag and `NewsArticle.image`, a reference that
is not a real fetched URL. A non-empty list means don't publish.
- `seo_audit` returns `must_fix` for the things that actually cost rankings —
a duplicate H1, a missing keyword in the opening, images with no alt text, a
meta description of the wrong length, fewer than two external source links.
Everything `fetch_article_facts` returns carries a `source_url`, so any claim in
the finished post can be traced back to the page it came from.

## No keys? Start here
With an empty `.env` the pipeline still runs end to end. Here is what you get,
and what each key would change.
| Step | With no key | With a key |
|---|---|---|
| Search | GDELT DOC 2.0 — official, free, no signup, news-specific — then Bing/Google News RSS as backup | Tavily / Brave / Serper / Google CSE: cleaner snippets, higher limits |
| Article extraction | Full quality. trafilatura runs locally. | — no key exists |
| Keywords | Full quality. Mined from your fetched sources, plus keyless Google autocomplete. | — a paid keyword API would add search-volume data |
| Humanise | Returns the rule set and asks the calling model to rewrite. Works well in Claude; varies elsewhere. | Rewrite happens server-side, identical everywhere |
| Human score | Local heuristic, labelled `is_real_detector: false` | A real detector's score |
| Image | Pollinations anonymous: ~1 request/15s, and **may watermark** | Cloudflare/OpenAI/Stability: clean, fast |
| Schema, audit, files | Full quality. | — no key exists |
### Search: what changed in 2026
**Brave is no longer the free recommendation.** In February 2026 Brave removed
its free tier and moved every plan to credit-based billing — a card is required,
a $5 monthly credit covers roughly 1,000 requests, and you are billed past that.
Free options that still hold up, best first:
- **GDELT** — no key, no signup, no limit to speak of. Already the default.
It is a global news index, so it is genuinely good at "is anyone reporting
this", which is exactly what `verify_news` asks. Start here and only add a key
if snippet quality or freshness becomes a problem.
- **Tavily** — 1,000 credits/month, renews monthly, no card. The best keyed
option for this pipeline. Set `TAVILY_API_KEY`.
- **Google Custom Search** — 100 queries/day, no card. Needs both
`GOOGLE_CSE_KEY` and `GOOGLE_CSE_ID` from
programmablesearchengine.google.com.
- **Serper** — 2,500 credits, no card, but one-time only. Fine for evaluating,
not for an ongoing blog.
- **NewsAPI** — free tier is non-commercial only and delays recent articles,
which is the wrong trade for breaking news.
Free tiers move around; check each provider's own pricing page before committing.
### Images: what you actually need
`generate_image` runs with no key, but read this before publishing anything.
Pollinations still allows anonymous requests — about one every 15 seconds, basic
models — but **the free anonymous tier may watermark the image**, which makes it
unusable as a published banner. Three ways out, cheapest first:
1. **Free Pollinations token** — register at auth.pollinations.ai, no card. This
removes the watermark and raises the rate limit. Set `POLLINATIONS_TOKEN`.
Smallest change, keeps the existing provider.
2. **Cloudflare Workers AI** (recommended) — FLUX schnell, a free daily
allowance, no watermark, and it is a real production API. Set
`IMAGE_PROVIDER=cloudflare`, `CLOUDFLARE_ACCOUNT_ID` and
`CLOUDFLARE_API_TOKEN`. Note the model returns 1024x1024, so crop to your
banner ratio.
3. **OpenAI Images or Stability** — paid per image, best quality.
Whichever you use, the file lands locally. Upload it and pass the public https
URL into `build_schema`, or `NewsArticle.image` points at a path no crawler can
reach.
### If you only add one key
Add **Cloudflare** (or the free Pollinations token) for images. Search already
works properly with no key; images are the step where the keyless output is not
publishable.
## Honest limitations
- **The human score is not proof of anything.** Public AI detectors have real
false-positive and false-negative rates, especially on short text and on
non-native English phrasing. The keyless fallback is not a detector at all —
it measures the structural tells the rewrite rules target. Present it as a
directional signal and say so wherever a reader sees the number.
- **The trademark filter is a safety net, not a legal opinion.** It rewrites
known brand terms into generic descriptors and strips logo requests before the
prompt leaves your machine. Extend `TRADEMARKS` in
`src/newsblog_mcp/providers/imagegen.py` as you hit new names, and still look
at what comes back.
- **Freshness is yours to set.** `find_stories(days=1)` is same-day; `days=2` is
the default. `verify_news` searches a 14-day window unless you pass `days`.
Feeding it a three-week-old headline returns three-week-old sources, correctly.
- **GDELT is an index, not an editor.** It indexes a very wide range of
publishers, including low-quality ones, so two GDELT "publishers" agreeing is
weaker evidence than two known outlets agreeing. Look at the domains in
`sources` before trusting a `medium` confidence. The RSS backups are
unofficial endpoints that can change shape without warning; `diagnose` tells
you when one has stopped working.
- **The SEO tools cover on-page only.** Keyword relevance, structure, meta
lengths, alt text, internal consistency. They say nothing about search volume,
competition, or backlinks — that needs a paid keyword API, and no free tier
gives real volume data.
- **Generated images are local files.** Upload the file and pass a public https
URL into `build_schema`, or `NewsArticle.image` will point at a path no crawler
can reach.
- **Corroboration is counted, not judged.** The server counts independent
publishers and flags date conflicts. Whether those publishers are all repeating
one wire story is a judgement the calling model still has to make.

Scored across 18 tools
Most tools have clearly distinct roles in a stepwise pipeline, and descriptions explicitly differentiate overlapping tools (e.g., score_ai_text vs find_ai_words, review_draft vs humanize_text). A few pairs—like the AI-detection tools and the profile-management tools—could still be momentarily confused, but the guidance resolves the boundary. Overall, an agent can reliably select the right tool.
Tool names are consistently snake_case and mostly follow a verb_noun or action-oriented pattern. Minor deviations like `capabilities`, `seo_keywords`, and `seo_audit` are noun phrases without explicit verbs, but they remain readable and predicable. The set is not chaotic.
18 tools is slightly above the ideal 3–15 range, but each tool corresponds to a distinct step in a complete news-blog composition pipeline. Given the end-to-end workflow (verification, fact extraction, SEO, drafting, publishing pack), the count is justified. Nothing feels redundant or padded.
The surface covers the full lifecycle from profile setup and story discovery through verification, fact extraction, SEO, drafting, review, image generation, schema building, and final packaging. There are no obvious dead ends for composing and saving a news blog post. Optional tools like humanize_text are clearly marked, and every major operation has a corresponding tool.
