Anydb MCP vs StackQL MCP Server
A side-by-side look at the Anydb MCP and StackQL MCP Server MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Anydb MCP for databases work as a local process; choose StackQL MCP Server for databases as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities
Anydb MCP tools 5
db_listList the connection profiles from the anydb config file (~/.anydb/db.json): name, description, driver, which one is the default, and whether it is read-only. Call this first whenever you do not already know a profile name, then pass the name to the other tools as "profile". The result never contains a connection string, a host, a username or a password -- not masked, absent -- because this text goes into your context window and a config file is writable by anyone who can write files. If there is no config file, use "uri" with the other tools instead.db_queryRun one statement against one database (PostgreSQL, MySQL/MariaDB, SQLite, MongoDB or Redis, inferred from the connection). READ-ONLY BY DEFAULT: writes are refused unless "readOnly" is false, and statements that change schema or privileges additionally require "allowDestructive" to be true. Call db_list and db_schema first so table and column names are not guessed, and prefer "params" over inlining values in "query" so the values never appear in the statement text. Put a LIMIT in every query: results are capped anyway, and a cap you did not ask for is how a table gets silently half-read. MongoDB: "collection" is required and "action" picks the operation -- find, count, distinct, aggregate and explain read; insert, update, updateOne, replace, delete and deleteOne write and need "readOnly": false. Prefer the *One actions: one document, not every match. Redis: "query" is a single command such as GET or SCAN.db_schemaDescribe the structure of a database: tables and their columns for SQL, collections with their indexes for MongoDB, keyspace statistics for Redis. Call it before writing a query so names are not guessed -- it is almost always cheaper than a failed query. Runs read-only introspection statements only, never a statement of yours, and "table"/"collection" are bound as parameters wherever the driver allows rather than pasted into SQL. "detail": "full" adds foreign keys, index definitions, primary and unique constraints, row estimates, and inferred field schemas for MongoDB.db_explainReturn the execution plan for a statement WITHOUT running it. Read-only by construction: the statement is planned and not executed, so this is the safe way to catch a sequential scan over a large table and the cheapest way to find a missing index. ANALYZE variants are refused here on purpose, because "EXPLAIN ANALYZE" runs the statement it plans. MongoDB: pass "collection" and a find filter as "query"; a pipeline cannot be explained, use db_query action "aggregate" with a small limit. Redis has no plans, so this tool refuses it.db_healthAsk the database about itself: reachable or not, server version, the role this server authenticated as, whether that role or the server is read-only, object counts, and this server's pool and cache state. Use it instead of guessing at why a connection or a write failed. Note what "readOnly": false does and does not do: it is a request to THIS server, not a security boundary. The boundary is the database role -- a role holding INSERT will succeed whatever these flags say, and a role without them will fail however many are set.
StackQL MCP Server tools 15
describe_methodFull I/O contract for one method: every input with its param_type (input_required params become exact-match WHERE predicates; input_optional ones may be added) and every output field, which are the columns a SELECT or RETURNING can reference. Call it after list_methods and before the first query against a method; there is no resource-level equivalent because each method returns its own shape. Requires provider, service, resource, method.list_methodsAccess methods (HTTP operations) for a resource with their SQL verb and required params. Pick the method whose verb matches the intent and whose required params you can supply, then describe_method it. Call when composing SQL from scratch against an unfamiliar resource; not needed when executing a vetted query library template. Requires provider, service, resource.list_providersAvailable cloud/SaaS providers (top of the hierarchy). No inputs.list_registryProviders (and their versions) available in the configured registry. Distinct from list_providers, which lists only providers already pulled. Optional provider arg lists versions for that provider.list_resourcesResources under a provider.service. Requires provider and service.list_servicesServices under a provider. Requires provider.pull_providerInstall a single provider from the registry into the local approot cache. Requires provider; version is optional (latest published is pulled when empty). Writes only local cache state; no cloud control/data plane effect.query_library_getRetrieve a query library entry by id. Without params: returns the raw template, param declarations and notes (adapt from it when no exact match exists). With params: the server validates values and returns rendered SQL plus which tool to execute it with (run_select_query or run_mutation_query). Read-only, no credentials.query_library_searchSearch the curated StackQL query library by natural-language intent. Returns ranked template ids. Consult before composing SQL from scratch; follow with query_library_get, which validates params and surfaces any the index omits. Read-only, no credentials.reload_credentialsLive-reload provider credentials: re-sources the server's configured env file into the process environment, invalidates cached auth contexts, and reports resolution status for every installed provider (optional provider arg filters the report; changed field flags values that differ from before). Never returns secret values. Credentials resolve automatically at query time - never call this at session start or before queries. Call only after a query fails with a credential resolution error (fix the env file first, then reload, then retry) or when the user says credentials have been rotated or changed. If the report shows changed: false after a failure, the file was not updated - ask the user rather than retrying.run_lifecycle_operationExecute a stackql EXEC lifecycle operation (eg EXEC aws.ec2.instances.start_instances ...). Real cloud side effects. Discover available operations and required params via list_methods and describe_method. Returns {messages, timestamp}. Gated by server mode.run_mutation_queryExecute INSERT/UPDATE/REPLACE/DELETE against the provider. Real side effects. Returns {messages, timestamp}. Gated by server mode. Consult query_library_search for a vetted template before composing SQL from scratch; when the SQL came from a library entry, pass its id as source.- +3 more on the listing page

Frequently asked questions
Anydb MCP is categorized under Databases and uses a local stdio subprocess. StackQL MCP Server belongs to Databases and uses a local stdio subprocess. Pick Anydb MCP for databases work and StackQL MCP Server for databases.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Anydb MCP is listed as free. StackQL MCP Server is listed as free. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add anydb-mcp and stackql-mcp-server as separate keys in the same mcpServers object, and your assistant will call tools from either one.
