Textcortex

TextCortex offers an AI-powered text generation API that enables developers to integrate advanced language models into their applications for tasks such as content creation, paraphrasing, and more.

Verdict

The Textcortex MCP brings AI writing assistance directly into your Switchy workspace. @mention it to generate email drafts with subject lines or condense long documents into summaries. Marketing teams use it to draft outreach at scale, support teams to templatize responses, and anyone drowning in meeting notes to extract key points. It handles two core tasks well — email composition and text summarization — but won't manage your calendar or pull data from other apps. You'll need a Textcortex API key to connect, which requires a paid account on their platform.

Common use cases

  • Draft cold outreach emails in seconds
  • Summarize customer feedback threads for review
  • Turn meeting transcripts into action items
  • Generate follow-up emails after sales calls
  • Condense research articles for team briefs

Setup

Setup guide

  1. 11. Open your Switchy workspace and navigate to Settings > Integrations > Browse MCP Servers. 2. Search for Textcortex and click Connect. 3. You'll be prompted to enter your Textcortex API key — generate one by logging into your Textcortex account at app.textcortex.com, going to Settings > API, and creating a new key. 4. Paste the key into Switchy and click Authorize. 5. Return to any Space in your workspace and type '@Textcortex' in a message to confirm the connection is live. 6. Test it by asking '@Textcortex draft an email to a prospect introducing our product' — you should see a subject line and body text generated within seconds. 7. If the MCP doesn't respond, double-check your API key hasn't expired and that your Textcortex account has active credits.

What teammates see: by default, memories from Textcortex are scoped to the Space (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

Example outputs

Illustrative - representative of the model's voice and quality, not literal recordings.

Prompt

@textcortex summarize this 3-page product spec into 3 bullet points for our standup

Output

Here's a concise summary of the product spec: • Core feature: Real-time collaboration canvas with version control, targeting design teams of 5-50 users • Technical approach: WebSocket-based sync layer with conflict resolution, estimated 8-week build • Success metrics: 80% daily active usage within pilot cohort, sub-200ms latency for concurrent edits This summary condenses the original spec's implementation details, user stories, and performance requirements into standup-ready talking points.

Notes

This example shows Textcortex's summarization strength for internal docs. The tool requires you to paste or provide the full input text first — it can't fetch documents from external sources. Best for turning meeting notes, specs, or research into digestible updates when you need a specific length or format.

Prompt

@textcortex generate an email to our beta users announcing the new API rate limits, keep it friendly and under 150 words

Output

Subject: Quick Update: New API Rate Limits Rolling Out Hi there, We're making a small change to keep our API fast and reliable for everyone. Starting next Monday, we're introducing rate limits of 100 requests per minute for free accounts and 500/min for Pro users. Most of you won't notice any difference — current usage data shows 95% of beta accounts stay well under these thresholds. If you do hit a limit, you'll get a clear error message with retry timing. Questions? Reply to this email or ping us in the beta Slack channel. Thanks for helping us build something great. Cheers, The Team (This is an illustrative draft based on your prompt parameters.)

Notes

Demonstrates email generation with tone and length constraints. Textcortex produces a subject line and body together, which saves a step when drafting announcements or outreach. You'll still need to review for accuracy and brand voice — the tool doesn't know your company's specific policies or user data, so treat output as a first draft requiring human verification.

Prompt

@textcortex take these 5 customer support tickets and draft a summary email for our product manager highlighting common themes

Output

Subject: Support Themes from Last Week's Tickets Here's what came up across the 5 tickets you shared: **Onboarding friction (3 tickets)**: Users struggled to connect their GitHub account during setup. Two mentioned the OAuth flow timing out, one couldn't find the "Connect" button on mobile. **Export feature requests (2 tickets)**: Both asked for CSV export of project data. One specifically needs it for compliance reporting. Recommendation: Prioritize the GitHub OAuth issue — it's blocking new signups. The export feature is lower urgency but worth scoping for Q2. (This synthesis assumes you provided ticket text in your prompt.)

Notes

Shows how Textcortex can synthesize multiple inputs into a structured summary with editorial framing. This workflow pairs the MCP's generation capability with your own analysis — you select which tickets to include, and the tool helps format findings for stakeholders. Requires API key authentication; no access to your actual ticketing system, so you must paste ticket content into the prompt.

Use-case deep-dives

Customer support email drafting

When Textcortex fits high-volume support teams with templated replies

A 6-person support team handling 200+ tickets daily needs fast, on-brand email responses without copy-paste fatigue. Textcortex's Generate Email tool works here because it takes a prompt (ticket context, tone, key points) and returns a draft subject line and body in seconds. The team shares a Switchy workspace with saved prompts for common scenarios—refund requests, feature questions, bug apologies—so anyone can generate a reply that sounds human without starting from scratch. The limitation: if your support flow requires pulling live data from Zendesk or Intercom (ticket history, customer tier), you'll need a separate MCP for that lookup first. Textcortex shines when the input is already in front of you and you just need the prose. If your team sends fewer than 30 emails a week, the overhead of managing API keys probably isn't worth it.

Meeting notes distillation for async teams

Use Textcortex to turn transcripts into action-item summaries

A remote 8-person engineering team records standups and planning calls, then needs someone to extract the decisions and next steps for Slack. Textcortex's Summarize Text tool handles this: paste the transcript, get a 3-paragraph summary that isolates commitments and blockers. The team keeps a Switchy thread for each sprint, feeding transcripts in as they arrive, so the summary history lives in one place. The trade-off: this MCP has no memory of previous summaries, so if you need to track recurring themes across weeks (like a blocker mentioned in three standups), you're manually connecting dots. It's fast and accurate for single-document distillation, but it won't replace a structured note-taking system. Best fit for teams that already have good meeting hygiene and just need the grunt work of summarization automated.

Sales follow-up personalization at scale

When Textcortex beats manual drafting for outbound sequences

A 3-person sales team runs outbound campaigns to 50 prospects a week, each needing a personalized follow-up after a demo. They use Textcortex's Generate Email tool in Switchy to draft replies based on demo notes (pain points discussed, features shown, objections raised). The workflow: after each call, the rep drops notes into a shared thread, prompts the tool with the prospect's context, and gets a draft that references the specific conversation. The win is speed—5 minutes per email becomes 90 seconds. The ceiling: if your team needs to pull CRM data (deal stage, previous emails, contract value) to inform the draft, Textcortex can't do that lookup itself. You'll feed it the context manually or pair it with a CRM MCP. Works best when your reps already take good notes and just need help turning them into polished prose.

Frequently asked

What does the Textcortex MCP do in Switchy?

It gives your team two AI writing tools: one generates email subject lines and body text from prompts, the other summarizes long content into concise versions. Both run inside Switchy's workspace, so you can pipe outputs into other MCPs or share drafts with teammates without switching tabs. Think of it as a lightweight copywriting assistant that lives where your work already happens.

Do I need a Textcortex account to use this MCP?

Yes. You'll need a Textcortex API key, which means you need an active Textcortex subscription. Grab the key from your Textcortex dashboard, paste it into Switchy's MCP settings, and the connection is live. No OAuth dance—just API key auth. One team member can connect it; everyone in the workspace can use the tools.

Can the Textcortex MCP write blog posts or long-form content?

Not really. The two tools are scoped to emails and summaries—short, focused outputs. If you need multi-paragraph blog posts or documentation, you're better off using Claude or GPT-4 directly in Switchy's chat. Textcortex shines when you want a quick subject line or a three-sentence summary, not when you're drafting a 1,500-word article.

How is this different from just using Textcortex's web app?

The MCP lives inside Switchy, so you can chain it with other tools—summarize a Notion doc, then generate an email about it, all in one workflow. The web app is faster if you're only doing one-off rewrites, but the MCP wins when you're building multi-step automations or collaborating with teammates who need to see the same outputs.

Does using this MCP count against my Textcortex usage limits?

Yes. Every time Switchy calls the Generate Email or Summarize Text tool, it hits Textcortex's API and counts toward your plan's monthly quota. If your team hammers the summarizer all day, you'll burn through credits faster. Check your Textcortex dashboard to monitor usage, and upgrade your plan if you hit the ceiling.
