Why the edge
Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.
Maintenance & community Neon MCP Server +72
Neon MCP Server 80
v2.0.0 on 5 November 2026, one day before this check (30). 1.0.0 (registry, 17 September) and 2.0.0 in the 90 days, two releases (10). 53 open issues and pull requests, with commits most days; reply times weren't measured (15). com.neon/mcp in the official registry, a domain-verified namespace, at 2.0.0 (15). Unit, integration and end-to-end test suites, knip and lint in CI (10). 30 + 10 + 15 + 15 + 10 = 80.
Postgres MCP Pro 8
Last release 0.3.0 on 16 May 2025 (0). No release in the last 90 days. Main has a batch of 11 merges from 19 to 22 January 2026 and one commit on 15 August 2026 (0). 37 open issues and 35 open pull requests, a request for a release (#162) open since March 2026 and no maintainer reply on the security report. A commenter on #187 says the project is unmaintained since Crystal DBA's acquisition by Temporal, which we couldn't confirm (5). Not in the official MCP registry. A lookup for io.github.crystaldba/postgres-mcp returns 404 (0). Dependencies were refreshed on main in January, but the published package has the unbounded mcp dependency that now breaks it (3).
Security & auth Neon MCP Server +43
Neon MCP Server 69
OAuth 2.1 with read and write scopes, per-project and per-role fixed grants, Client ID Metadata Documents and RFC 9207 iss on redirects, or API keys (28). Read-only mode keeps SQL in READ ONLY transactions and withholds connection strings, roleName limits SQL to a role's grants, and destructive tools ask the model to confirm with the user; with an API key anyone who can edit the URL can widen the grant (17). The README warns to review every action and keep the server away from production, but we found no prompt-injection guidance for query results (5). Neon has project audit logs, but we didn't read whether MCP calls appear (5). SOC 2 Type II with a public SOC 3, ISO 27001 and 27701, HIPAA; no security.txt on neon.com (14). 28 + 17 + 5 + 5 + 14 = 69.
Postgres MCP Pro 26
One database URI from DATABASE_URI or the command line, with whatever privileges its role has. The SSE and HTTP transports have no authentication and bind to localhost by default (10). Restricted mode parses every statement with pglast against an allowlist of statement types and functions, runs it in a read-only transaction and stops it after 30 seconds. But unrestricted is the default, every config example in the README uses it, and #178 (opened 6 June 2026) shows restricted mode reading server files through a function in the FROM clause. The fix (#200) is unmerged (10). The README discusses LLM-generated damage at length but says nothing about instructions hidden in table data, and rows reach the model unmarked (3). Restricted-mode queries are tagged /* crystaldba */, so they can be picked out in Postgres logs and pg_stat_statements (3). No SECURITY.md, and the #178 reporter says private advisories aren't enabled (0).
Schema & documentation Neon MCP Server +34
Neon MCP Server 90
Every tool has a JSON Schema, many generated from the Neon OpenAPI spec (25). neon.com serves llms.txt and Markdown pages (10). Descriptions say when and when not ("branch_id is a branch id, not a branch name. Call list_branches to resolve a name", "NEVER run autonomously") (18). Typed inputs with enums such as access read_only or read_write, and path arguments checked for . and .. since 2.0.0 (13). Examples in the README and docs, and API 4xx errors classified by kind (11). CHANGELOG with dated releases and a registry version (13). 25 + 10 + 18 + 13 + 11 + 13 = 90.
Postgres MCP Pro 56
FastMCP builds typed JSON Schema for all nine tools from Python type hints (25 less 5, since hypothetical_indexes is a list of free-form dicts) (20). No llms.txt. The README is Markdown on GitHub with a tool table (5). explain_query warns that analyze runs the query and analyze_db_health lists its checks, but most descriptions are one line ("List objects in a schema") and none says when not to use a tool (10). method is an enum. object_type, health_type and sort_by are free strings with valid values only in the prose, limit has no bounds and execute_sql gives sql a default of "all" (7). explain_query carries two worked examples. Errors come back as "Error: <Postgres message>" text (9). Semver tags, no changelog (5).
Reliability Neon MCP Server +31
Neon MCP Server 72
Hosted reading. neonstatus.com on status.io with components per region, though no MCP component (20). The page shows only the last 30 days, three incidents, a partial disruption of monitoring data on 21 October (1 hour 22 minutes), slow compute starts in us-east-2 on 2 November (2 hours 14 minutes) and 26 minutes of console and API errors on 2 November; August and September weren't readable (15). The Neon API publishes 700 requests a minute with a 40-a-second burst per route (15). 429 with exponential backoff advice and 423 Locked for overlapping operations with retry guidance, but no idempotency keys (12). An uptime SLA on Scale only, with no percentage on the pricing page (5). The docs give the server no status label and the README says it isn't recommended for production (5). 20 + 15 + 15 + 12 + 5 + 5 = 72.
Postgres MCP Pro 41
Scored as a local stdio package. postgres-mcp on PyPI and the crystaldba/postgres-mcp Docker image, Python 3.12 or later stated. But PyPI's only current release, 0.3.0 from May 2025, asks for mcp[cli]>=1.5.0 with no ceiling, and since MCP Python SDK 2.0.0 shipped on 28 July 2026 a fresh uvx postgres-mcp pulls it and fails with "No module named 'mcp.server.fastmcp'" (#187). The <2.0 pin landed on main on 15 August and hasn't been released (10). CI runs ruff, pyright and pytest with a Postgres container on every push and pull request, with 25 unit test files. We couldn't see whether main passes (20). 37 open issues, among them the broken install, failures on custom schemas (#181) and two unmerged pull requests for connection-pool leaks (#177, #195) (6). Semver tags with no changelog (5). Pre-1.0 (0).
Agent ergonomics Neon MCP Server +22
Neon MCP Server 79
138 tools with no grant, far over 30 (5), with category, projectId and readonly to cut the list (plus 10). List tools take limits and cursors from the API, and describe_branch returns a tree (16). API errors return with their kind and status, path errors are tool errors, and unknown categories come back as a notice (16). readOnlyHint and destructiveHint on every definition, and the grant filter tells the model never to run destructive tools autonomously (18). Official TypeScript and Python SDKs for the Neon API; a no-auth tool preview endpoint (14). 15 + 16 + 16 + 18 + 14 = 79.
Postgres MCP Pro 57
Nine tools with about 2,500 characters of descriptions, roughly 1,300 tokens of definitions by our estimate (23). get_top_queries takes a limit, but execute_sql returns every row and the index tools append a _langfuse_trace block by default unless POSTGRES_MCP_INCLUDE_LANGFUSE_TRACE=false (6). Restricted mode explains its refusals (Only SELECT, ANALYZE, VACUUM, EXPLAIN, SHOW and other read-only statements are allowed) and its 30-second timeout suggests simplifying the query. Errors arrive as ordinary text rather than flagged tool errors (13). Annotations exist on main since January 2026 but not in the released 0.3.0, and on main explain_query claims readOnlyHint though analyze: true executes the statement in unrestricted mode (5). Sensible defaults, at most one required parameter per tool. Python only, plus Docker (10).
Payments & pricing Postgres MCP Pro +20
Neon MCP Server 40
No x402, MPP or L402 (0). Per-unit prices are public, compute per CU-hour and storage per GB-month (20). Free plan with no card (20). A person signs up and authorises in a browser; the CLI can mint a key only after a login (0). 0 + 20 + 20 + 0 = 40.
Postgres MCP Pro 60
Free, self-hosted, nothing to buy, so 20 + 20 + 20. No payment protocol (0). The optional llm index method needs your own OpenAI key.

Verdicts
Neon MCP Server
OAuth with read or write scopes, per-project and per-role grants, read-only SQL in READ ONLY transactions, and migrations tried on temporary branches. With no grant it lists 138 tools, the README advises against production use, and it sends account name and email to Segment with no opt-out for hosted users.
Postgres MCP Pro
Index tuning with hypopg, EXPLAIN with hypothetical indexes, top queries and seven health checks. No release since 0.3.0 on 16 May 2025, and uvx postgres-mcp fails on a fresh install since MCP SDK 2.0.
Before you call either
Neon MCP Server
- Connect with ?category=querying&category=schema&projectId=... or untick Allow writes at consent to cut 138 tools to a handful
- Use prepare_database_migration and complete_database_migration for schema changes, and ask the user before completing
- Pass branch IDs (br-...), not names; call list_branches to resolve a name
- On 429 back off exponentially, and on 423 Locked wait for the running operation to finish
Postgres MCP Pro
- Launch with
uvx --with 'mcp<2' postgres-mcp. Plainuvx postgres-mcpnow fails with "No module named 'mcp.server.fastmcp'" - Pass
--access-mode=restrictedexplicitly. The default is unrestricted - Connect with a role that lacks superuser and pg_read_server_files. Restricted mode alone doesn't stop server file reads
- Put
LIMITin everyexecute_sqlquery. The server returns every row - Don't set
analyze: trueonexplain_queryfor writes in unrestricted mode. It runs the statement
