Pylar
Pylar turns your SQL views into governed MCP tools so AI agents only see the data you approve.
If security asked why an agent holds a Snowflake credential, Pylar is the answer that gets approved: views are the only access level, secrets are KMS-isolated, and MCP tools run predefined SQL only — published once to a single MCP HTTP URL that drops into Claude Desktop, Cursor, n8n or LangGraph. Pricing starts at $20/mo for 5,000 agent executions, moves to $49/mo (10,000 executions, up to 3 data sources) and $199/mo for Growth (25,000 executions, evals, audit logs, SSO). The execution counter is the catch — a busy support bot burns 5,000 quickly. Weigh it against hand-building MCP servers (weeks of auth and endpoint work) or raw read replicas (no per-tool row-level control). Pilot on

Skip Pylar if you need an agent that reads unstructured web pages or reacts to events in real time, or if your agent fleet already burns more than a few thousand tool calls a month and you want to stay on a sub-$50 plan.
Starter's 5,000 monthly agent executions count tool invocations, query executions and data retrievals, so a busy production agent can hit the cap well before month-end.
Pylar's $20/mo Starter and $49/mo Team tiers undercut hand-built MCP servers on engineering time, and sit below general-purpose data governance platforms that charge enterprise minimums. It is more expensive than a bare read replica or a self-hosted MCP server you maintain yourself, and the $199/mo Growth tier — where evals, audit logs and SSO live — is the real entry point for security-reviewed deployments. Small teams should budget for Team or Growth, not Starter.

About Pylar
Pylar is a governed data access layer that sits between your AI agents and your databases. Instead of handing agents raw tables, you define SQL views — in a visual SQL editor, handwritten SQL, Malloy, or plain-language AI chat — and Pylar compiles each view into one or more MCP tools published behind a single MCP HTTP streaming URL and bearer token. That one connection works across Claude Desktop, Cursor, Windsurf, VS Code, LangGraph, OpenAI Platform, Zapier, Make, and n8n, and edits you make in Pylar propagate to every connected builder without redeploying agents. Data plumbing runs two ways. Bring your own warehouse — Snowflake, BigQuery, Postgres and others — and join across them in a single query with no data movement; views enforce row-level security and column filtering so PII stays out of agent context. Or, with no warehouse, Pylar hosts a managed one and ingests from 100+ connectors across sales (HubSpot, Salesforce, Pipedrive, Close, Outreach), support (Zendesk, Intercom, Front, Help Scout, Freshdesk), marketing, product analytics (Amplitude, Mixpanel, PostHog, Heap, FullStory), finance (Stripe, QuickBooks, Xero, Chargebee, Recurly) and collaboration tools (Google Sheets, Airtable, Notion, Linear, Asana), handling ETL, schema mapping, incremental syncs and cleaning. The security model is the product: credentials are isolated and stored with cloud KMS, agents never touch the warehouse directly, and MCP tools execute only the predefined SQL in the view. Evals tracks success rate, p95 latency, hit rate, cost per call and violations per tool; audit logs and access history arrive on Growth, RBAC and project organization from Team up. Pylar is built for the data engineer, platform team or CTO asked to let AI touch production data without hand-rolling auth, endpoints and auditing. It is batch-sync oriented, so teams needing unstructured web data or real-time streaming should look elsewhere.
Behind the Verdict
Pylar's core insight is that the dangerous part of giving an agent database access isn't the model — it's the credential. So it never lets the agent have one. You connect Snowflake, BigQuery or Postgres, write a view (the SQL editor, Malloy files and an AI chat assistant all feed the same view layer), and Pylar compiles that view into one or more parameterised MCP tools. The published artifact is a single MCP HTTP streaming URL plus bearer token; agents call get_customer_health, not SELECT * FROM customers. What works well: cross-database joins without data movement, row-level security and column filtering enforced at the view, and the publish-once-propagate-everywhere model — change a view and Claude Desktop, Cursor, Windsurf, VS Code, n8n, Make, Zapier, LangGraph and OpenAI Platform all pick it up without a redeploy. For teams with no warehouse, the managed path covers 100+ connectors (HubSpot, Salesforce, Zendesk, Intercom, Stripe, QuickBooks, Google Ads, Mixpanel and more) including ETL, schema mapping and incremental syncs, which is genuinely a lot of pipeline work you don't have to do. What it isn't: a chatbot, or a scraper. It governs structured views only — batch-synced data, not real-time streaming or event-driven workloads — and it assumes you already have an agent builder you like. Evals (success rate, p95 latency, hit rate, cost per call, violations per tool), audit logs, access history and SSO are gated behind Growth at $199/mo, so a security-conscious team outgrows the $20 and $49 tiers fairly quickly. The execution counter — 5,000 on Starter, 10,000 on Team, 25,000 on Growth — is the number to model before you ship, because a production support agent will find it.

Real-world workflow fit
Concrete scenarios for the personas Pylar actually fits — and what changes day-one when you adopt it.
Connect the existing Postgres and Snowflake instances to Pylar, write one cs_support view with a row-level filter, and use the AI chat assistant to generate a parameterised get_customer_health MCP tool.
Outcome: One MCP HTTP URL and bearer token pasted into Claude Desktop and Cursor; the support agent answers customer questions from governed data and no engineer hands out a warehouse credential.
Use Pylar's managed warehouse to sync HubSpot, Stripe and Zendesk via connectors, then build a customer_360 view joining contacts, subscriptions and tickets.
Outcome: An n8n workflow calls the published MCP tools the same afternoon; syncs run incrementally and nothing pipelines was hand-built.
Stand up a Growth-tier project on $199/mo, turn on Evals and audit logs, and give each department its own project with role-based access control.
Outcome: Per-tool success rate, p95 latency, hit rate and cost per call are visible to the platform team, and the access history satisfies the security review before the agents go live.
Use Cases
- Give a support agent live ticket and subscription data without exposing raw Snowflake tables.
- Create a customer health tool that joins Postgres and HubSpot data automatically.
- Publish MCP tools to Cursor for an internal ops agent querying billing and usage metrics.
- Sandbox a Stripe and Zendesk view for an agent that checks refund eligibility.
- Build a churn prediction tool over a SQL view of user activity and support tickets.
- Connect HubSpot, Stripe and Zendesk through managed connectors with no warehouse to stand up.
- Expose a parameterised get_customer_health tool that returns metrics by email.
- Run the same governed data across n8n, LangGraph and Claude Desktop from one MCP URL.
Limitations
- Agent executions are plan-gated: 5,000/mo on Starter, 10,000 on Team, 25,000 on Growth, unlimited on Enterprise.
- User seats and data source connections also vary by tier (Starter caps at 1 data source and 3 users; Team at 3 sources and 5 users).
- SSO, the Evals dashboard, audit logs and access history are restricted to the Growth tier and above, so security-conscious teams can't stay on $20 or $49.
- Overages are not addressed on the pricing page.
- Pylar governs structured views only — no unstructured web data or scraping — and sync is batch-oriented rather than real-time.

Plans compared
For each published Pylar tier: who it actually fits, and what it adds vs. the previous tier. Cross-reference the cost calculator above for projected annual outlay.
Starter
$20/mo
Ideal for
A single team piloting its first agent against one warehouse or one managed connector, with 5,000 executions a month to spare.
What this tier adds
Starting tier at $20/mo: 5,000 agent executions, up to 3 users, 1 data source connection, unlimited SQL views and MCP tools.
Team
$49/mo
Ideal for
A team running agents across two or three use cases who needs a second and third data source plus project separation.
What this tier adds
Doubles executions to 10,000/mo, lifts users to 5 and data sources to 3, and adds project organization, role-based access control and email support.
Growth
$199/mo
Ideal for
An organization scaling agents across departments that has to pass a security review before going to production.
What this tier adds
$199/mo raises executions to 25,000, removes the user cap, allows 5 data sources, and unlocks the Evals dashboard, audit logs, access history, SSO and priority support.
Enterprise
Custom
Ideal for
Regulated enterprises deploying agents at scale that need private cloud or on-prem deployment and contractual SLAs.
What this tier adds
Custom pricing for unlimited executions, users and data sources plus private cloud or on-prem hosting, custom authentication and SSO, and advanced compliance and audit.
Where the pricing makes sense
The company stage and team size where Pylar's pricing actually pencils out — and where peers do it cheaper.
Pylar's $20/mo Starter and $49/mo Team tiers undercut hand-built MCP servers on engineering time, and sit below general-purpose data governance platforms that charge enterprise minimums. It is more expensive than a bare read replica or a self-hosted MCP server you maintain yourself, and the $199/mo Growth tier — where evals, audit logs and SSO live — is the real entry point for security-reviewed deployments. Small teams should budget for Team or Growth, not Starter.
Setup time & first value
How long it actually takes to get something useful out of Pylar — broken out by persona, not the marketing-page minute.
Data engineer with an existing warehouse: roughly 10 minutes from connecting a source to a published MCP tool if the view already exists, and an afternoon for a full view and tool set. RevOps team with no warehouse: expect hours rather than minutes, because connector syncs and schema mapping have to finish before views return data. Enterprise on-prem or private-cloud deployment runs on a custom
Switching to or from Pylar
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From hand-built MCP servers: point agents at Pylar's single MCP HTTP URL instead of your bespoke endpoint, then reimplement each tool as a view-backed MCP tool.
- →From raw read replicas: recreate the tables you exposed as views with row-level security and column filtering.
- →From direct database credentials in agent builders: revoke the credentials as each Pylar MCP tool goes live in Claude Desktop, Cursor, n8n or LangGraph.
- →From a DIY connector pipeline: let Pylar's managed warehouse take over ingestion, schema mapping and incremental syncs for CRM, billing and support sources.
- ↗To a self-hosted MCP server: export the governing SQL from each view and rebuild the tool definitions behind your own endpoint and auth.
- ↗To another governance layer: recreate views and row-level rules in the successor, then swap the MCP HTTP URL in each connected agent builder.
- ↗To raw warehouse access for internal tools: reissue scoped database credentials where agents no longer route through Pylar.
