# PlanetScale MCP Server (slim)

> PlanetScale's hosted MCP server connects agents to PlanetScale Postgres, Vitess and Neki databases. Its 25 tools cover organisations, branches, schema, read and write SQL, Insights data, Postgres logs, invoices and documentation search, with OAuth or a service token.

**B · 66.4/100 · rank #292 of 950 · #5 in Databases & files · not agent-ready · confidence medium**


Assessment: OAuth scopes set no, read-only or full database access per organisation or database, each query runs on a credential created and deleted for that call, and an insights-only endpoint drops both SQL tools. Destructive statements are gated by a flag the model sets itself, no rate limit was found, and every plan needs a card.

## Facts

- Kind: MCP server · vendor: PlanetScale · category: Databases & files · legal entity: PlanetScale, Inc. · provenance 73/100
- Endpoint: `https://mcp.pscale.dev/mcp/planetscale` (Streamable HTTP)
- Auth: OAuth or key · pricing: Paid · x402: no · licence: Proprietary hosted service under PlanetScale's Terms of Service. The 13 tools in planetscale/mcp-server are Apache-2.0
- Probe metrics: not measured yet (probes haven't run)
- Endpoints: https://mcp.pscale.dev/mcp/planetscale (all 25 tools) and https://mcp.pscale.dev/mcp/planetscale-insights-only (no SQL tools). Streamable HTTP
- Tools: 25. Organisations, databases and branches (list and get), branch schema, read query, write query, Insights, schema recommendations, query error patterns and executions, query tags and summaries, Postgres logs, regions, cluster sizes, invoices and line items, payment method (show, update, setup status), documentation search
- Databases: PlanetScale Postgres, Vitess (MySQL) and Neki (sharded Postgres, in platform preview since 10 September 2026)
- Credentials: OAuth with per-client registration and scopes of no, read-only or full access per organisation or database, plus a separate payment-method scope. Service tokens (`pscale_tkn_`) as a Bearer header for CI and headless clients, with per-permission grants
- Query safeguards: Per-call database credentials deleted after use. Reads go to a replica by default. TRUNCATE and unfiltered UPDATE or DELETE blocked. DELETE and DDL need `confirm_destructive`. 50-second limit. Queries tagged `source=planetscale-mcp`
- Rate limits: None found for the MCP server or the API. The OpenAPI file lists a 429 response with no figures
- Output limits: Insights 5 results a metric by default, 20 at most. Error, tag and log tools take `limit` and report `truncated` or `has_next`. Query tools return all rows
- Source: github.com/planetscale/mcp-server, Apache-2.0, 13 of the 25 tools, built on `@gram-ai/functions`. Package version 0.0.0, no tags, 100 commits from 24 January to 17 September 2026
- Registry: `io.github.planetscale/mcp-server` 1.0.0 in the official MCP registry, published 15 April 2026. Also in the Claude connectors directory and as a Claude Code plugin, per the docs
- Free tier: None found. All plans need a payment method on file
- Prices: AWS us-east-1. Postgres single node from $5 a month (PS-5), Postgres with two replicas from $15, Vitess from $39 (PS-10), Neki from $30 a shard. Storage, backups and egress are billed separately
- SLA: 99.99 per cent for single-region and 99.999 per cent for multi-region clusters, service credits of 10 to 50 per cent. Single-node clusters and beta functions excluded (updated 27 August 2026)
- Status: planetscalestatus.com on incident.io, components by engine, cloud and region, plus Database Operations, Dashboard and API Requests, and Query Insights
- Certifications: SOC 1 Type 2 and SOC 2 Type 2 with HIPAA on all plans, PCI DSS 4.0.1 Level 1 for PlanetScale Managed, reports through trust.planetscale.com (not read)
- Audit: Organisation audit log and security log on all plans. Installed OAuth apps can be reviewed and revoked since 28 September 2026
- Prices: Postgres PS-5, single node $5 per month (plan); Postgres PS-5, primary and two replicas $15 per month (plan); Vitess PS-10, primary and two replicas $39 per month (plan)

## Before you call it

1. Use `https://mcp.pscale.dev/mcp/planetscale-insights-only` when the task needs no SQL. It omits both query tools
2. Pass `organization`, `database` and `branch` on every query call. Record them in `AGENTS.md` to skip the listing calls
3. Show the person the exact DELETE or DDL statement and get approval before setting `confirm_destructive: true`
4. Keep queries under 50 seconds and add your own `LIMIT`. The query tools cancel at 50 seconds and return every row
5. For a service token send `Authorization: Bearer pscale_tkn_...` with the secret only. The `id:secret` form is rejected
