Directory
22 official connectors grouped by category
Le Chat speaks MCP (Model Context Protocol), an open standard published by Anthropic. Mistral announced its connectors on September 2, 2025. Up-to-date list (May 2026) per the official Mistral announcement.
For developers
GitHub, Linear, Sentry, Cloudflare Development Platform
Wire your issues, PRs, sprint board, monitoring. Le Chat can brief on recent tickets, explain a PR, generate release notes, read Sentry errors, deploy to Cloudflare Workers. Standard OAuth 2.1 auth.
Concrete case: a frontend dev wires GitHub + Linear + Sentry, asks each morning for a brief of priority issues and prod errors. Configure once, use daily.
For data teams
Snowflake, Databricks, Pinecone, Prisma Postgres, DeepWiki
Wire your warehouse, vector DB, or knowledge base. Le Chat can write and run SQL queries, explain schemas, summarize tables, query a vector index. Read-only by default for safety.
Snowflake and Databricks were marked 'coming soon' at the September 2025 announcement. Check current status in the Connectors directory.
Development
GitHub
Issues, PRs, code, releases, projects.
The GitHub connector lets you brief issues, explain pull requests, generate release notes, read source code, manage projects. Auth via standard GitHub OAuth. Explicit confirmation before each write.
Data
Snowflake
Query your warehouse in natural language.
Le Chat can write and run Snowflake SQL queries, explain schemas, build dashboards, do ad-hoc analyses. Auth via SSO or key pair. Read-only by default.
Productivity
Atlassian (Jira / Confluence)
Jira tickets and Confluence pages.
Read Jira tickets, generate tickets from a description, search Confluence, read pages. Auth via Atlassian OAuth. Concrete case: a PM asks each Monday 'summarize the open tickets in Confluence on project X'.
Commerce
Stripe
Transactions, subscriptions, customers.
Le Chat can query your Stripe dashboard: MRR, churn, top customers, unpaid invoices. Read-only by default. Useful for business reviews without opening the dashboard.
Development
Linear
Dev tickets and roadmap.
Le Chat reads your Linear workspace: issues, projects, cycles. Can generate issues from a description, brief the current sprint. Auth via Linear OAuth.
Productivity
Notion
Pages, databases, knowledge base.
Search and read your Notion pages, generate structured content, work with databases. Auth via Notion OAuth. Confirmation required to write.
Automation
Zapier
Access 6000+ apps via Zapier.
The Zapier connector opens up the entire Zapier ecosystem - over 6000 third-party apps (Slack, Gmail, Trello, etc.). Read mode for most, write on explicit request. More flexible than native connectors for niche tools.
Data
Databricks
Notebooks, Unity Catalog, ML.
Connect your Databricks workspace. Le Chat can query Unity Catalog, run notebooks, read Delta tables. Auth via Databricks SSO. Status: coming soon at September 2025 announcement, check current directory.
Productivity
Box
Cloud files, team sharing.
Access your Box files. Le Chat can read documents, summarize them, classify files. Especially useful for regulated teams that use Box for compliance.
Productivity
Asana & Monday.com
Classic project management.
Read and generate tasks in Asana or Monday.com. Le Chat can brief a project, identify blockers, generate a progress report. Standard OAuth auth for both.
Commerce
PayPal, Plaid, Square
Three payment / banking connectors.
PayPal for e-commerce payments, Plaid for banking (account reads, transactions), Square for retail POS. Read-only on sensitive data. Concrete case: a weekly financial brief crossing all three.
Advanced
Custom MCP server
Wire any MCP server.
Settings -> Connectors -> Add custom. Paste a remote MCP server URL. Le Chat configures it automatically, handles auth (OAuth 2.1 / Bearer / no auth). Compatible with the entire MCP ecosystem (Anthropic Claude, Cursor, Windsurf use the same protocol).
Why MCP
Open protocol advantage vs GPT Store
MCP is open, multi-vendor, easier to wire to internal systems.
Open and multi-vendor
MCP is a standard published by Anthropic in November 2024, adopted by Mistral (September 2025), OpenAI Agents SDK (March 2025), Cursor, Cline, GitHub Copilot. You are not locked in. If you swap models, connectors keep working.
Easier for internal systems
Build your own MCP server in hours with Python (FastMCP, 23k stars on GitHub) or TypeScript (official SDK, 12.4k stars). Wiring your home-grown CRM, internal data, or private APIs becomes direct.
No closed Store
No need to submit your connector to a marketplace. Deploy on your infra, Le Chat calls it directly. Good for confidentiality and sovereignty. The official MCP registry (registry.modelcontextprotocol.io) counts 9,400+ servers as of April 2026.
Standard auth, clean audit
MCP uses OAuth 2.1 (with dynamic client registration), API keys, or no auth for public servers. Every action requires explicit user confirmation. For compliance teams, more auditable than closed plugins.
Limits to know
Three limits of MCP in 2026
MCP is good but not perfect. Know these before migrating everything.
Limit 1: fewer consumer-grade connectors than GPT Store
- GPT Store has hundreds of thousands of custom GPTs.
- MCP has 22 official connectors at Mistral, 9,400+ servers total in the public registry.
- For niche consumer tools, ChatGPT keeps the volume advantage.
- MCP catches up fast: 18% monthly registry growth.
Limit 2: writes need more care
- Most connectors are read-only by default.
- Writing (create a Jira ticket, send mail) requires explicit per-action authorization.
- Safer, but slightly different workflow.
- Critical production: destructive operations should be wrapped in a custom connector.
Limit 3: security vulnerabilities to know
- Tool Poisoning: malicious tool description invisible to the user.
- Prompt Injection: content returned by an MCP server can contain instructions.
- MCPTox academic study: attack success rate up to 72.8% across 45 real servers.
- Advice: audit any third-party MCP server before wiring it in prod, especially in enterprise.
For developers
Build your own MCP server
The MCP protocol is open. Official Python and TypeScript SDKs.
Canonical protocol site. Current spec: 2025-11-25. Host / Client / Server architecture, JSON-RPC 2.0, stdio and Streamable HTTP transports.
pip install mcp[cli] or uv add mcp[cli]. FastMCP decorators: 20 lines for a working server. Ideal for prototyping.
npm install @modelcontextprotocol/sdk. Compatible with Node, Bun, Deno. Schema validation via Standard Schema. v1.29.0 released March 2026.
Reference implementations by Anthropic: Google Drive, Slack, GitHub, Git, Postgres, Puppeteer. Great starting examples.
9,400+ public MCP servers as of April 2026, 18% monthly growth. Searchable catalog. Source of truth for discovering community connectors.
2026 priorities: scalable Streamable HTTP, agent communication, audit trail, enterprise SSO. To plan your integration long-term.
Security and compliance
What legal teams need to know
Three essential references before deploying in enterprise.
Analysis of major vulnerabilities: Tool Poisoning, Prompt Injection, Conversation Hijacking, Covert Tool Invocation. Required reading before prod.
Pragmatic analysis of injection risks via MCP by a recognized expert. Good starting point for understanding real attack surfaces.
SAML 2.0 SSO for Le Chat Enterprise. Compatible with Okta, Entra ID, Google Workspace. SCIM provisioning: status not confirmed in official docs.
