Common questions

Is MCPDBWizard safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.29) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

MCPDBWizard

An MCP server for Oracle, built from the objects you choose. Tick the PL/SQL packages, tables, sequences and your own tested SQL statements in a console, and it generates a Model Context Protocol server exposing exactly those to an AI agent as typed tools — each carrying a JSON Schema derived from the procedure's real signature.

There is no `run-sql` tool. Anything you did not select has no tool, no method and no class: it is absent from the binary rather than refused at run time. Nothing composes a query at run time either — the generated code is ordinary Java with fixed SQL statements and typed binds, and the MCP server calls those wrappers rather than writing SQL for a model to run.

Generating that server means generating the whole calling layer, so you get it too: typed DAO factories, callable-statement wrappers, table managers and an optional SOAP layer. They are useful on their own, but the MCP server is the point.

Supports Oracle 12c through 26ai, and is regression-tested against six live instances spanning that range.

*How the full product fits together. This repository is the generator — the config file, generate & compile, and the generated MCP server. The Design pages, Runtime page and proxy are the web console in the Docker image; here you select objects with the Swing tool or a config file instead, and the generated server can be run on its own.*

The part that is hard

The usual way round is to hand the agent a run-sql tool, and it works until the schema is real: published text‑to‑SQL accuracy falls sharply on enterprise‑scale schemas compared with tidy benchmarks, and a wrong UPDATE is not a wrong answer, it is an incident.

The alternative is curated tools — but writing one per procedure by hand does not scale past a few, and PL/SQL is unusually hostile to deriving them automatically:

a procedure can have any number of OUT and IN OUT parameters, not a single return value
parameters can be records (including records nested inside records), collections, `%ROWTYPE`s, REF CURSORs, package types, and overloads
Oracle's own data dictionary describes these differently between versions

This project does that derivation. Every generated MCP tool carries a real JSON Schema built from the procedure's actual signature, so the agent is *told* what the parameters are rather than inferring them from prose.

oracle:  PROCEDURE order_summary(p_customer IN  NUMBER,

p_totals OUT summary_rec, p_lines OUT SYS_REFCURSOR)

tool: order_summary { "p_customer": } -> { "p_totals": { "orderCount": 12, "value": 4210.55 }, "p_lines": [ { "sku": "AB-1", "qty": 3 }, ... ] }

A record crosses as a JSON object, a REF CURSOR as an array of row objects, a DATE as an ISO‑8601 string, RAW and binary vectors as base64, CLOB as text, BLOB as base64.

Quick start

Requires Java 21 and Maven. The Oracle JDBC driver (com.oracle.database.jdbc:ojdbc11) comes from Maven Central — nothing to install by hand.

mvn clean package

That produces two jars in target/: a plain one, and a self‑contained mcpdbwizard-app- -shaded.jar with the driver bundled.

# Interactive (Swing) -- pick objects and options, save a config

java -jar target/mcpdbwizard-app-*-shaded.jar myconfig.pb2

Batch -- regenerate from a saved config

java -jar target/mcpdbwizard-app-*-shaded.jar build myconfig.pb2

is created if missing.

Changed in 2026-08: there used to be a leading argument. It has been

removed, and a command line that still passes one will be read as the log directory.

It was validated for shape only — ≥19 characters, not a path, not the literal build —

and then ignored, so it authenticated nothing. Drop it from any script that supplies it.

Configs are .pb2 (a flat properties file) or .json; both are accepted, and convert losslessly either way:

java -cp target/mcpdbwizard-app-*-shaded.jar \

com.mcpdbwizard.schema.ConfigConverter myconfig.pb2 myconfig.json

What gets generated


DAO factory	one entry point per config, wiring connections and logging
PL/SQL wrappers	a class per procedure/function — `setParamX`, `executeProc`, `getParamY`
Table managers	row CRUD by primary key, plus unique‑key, index and foreign‑key‑child lookups
SQL statement classes	your own SQL, with typed bind parameters
SOAP service layer	optional
JSON / JSON‑RPC connectors	optional
MCP server	optional (needs Java 17+ for the MCP SDK)

Generated code depends only on com.mcpdbwizard.pub, the runtime library in this repository.

The MCP server

A single generated McpServer.java, speaking stdio by default or Streamable HTTP when started with http [port]. Optional bearer‑token auth and TLS both read their secrets from the environment at run time and fail closed if unset, so no secret is baked into the generated source.

It exposes PL/SQL routines, table row CRUD and secondary lookups, user SQL statements, sequences, and — on 23ai — JSON‑relational duality views with document CRUD and etag optimistic locking.

What is exposed is decided when you generate, not at run time. An object you did not select has no code generated for it at all, and TABLE_MCP_CRUD_ narrows a table to any subset of create/read/update/delete. An operation that is not exposed has no tool method emitted — it is absent from the binary, not merely unregistered.

Oracle datatype support

Beyond the ordinary scalars and LOBs: 12c identity columns and extended VARCHAR2/RAW; 21c native JSON; 23ai native BOOLEAN, VECTOR (dense, binary and sparse), and JSON‑relational duality views.

Known gaps: TIMESTAMP WITH [LOCAL] TIME ZONE and BFILE cross as procedure parameters but not yet as table columns; SDO_GEOMETRY has no JSON mapping, so a routine using one is skipped; FLOAT16 vectors are blocked server‑side.

Logging

Generated factories pick a LogInterface implementation from the config: console, text file, java.util.logging, Log4j 1.x, SLF4J, or Log4j 2. The SLF4J and Log4j 2 backends live in com.mcpdbwizard.pub and depend only on the facade jar, which is an optional dependency — supply the api plus a binding yourself if you use them.

Tests

The database‑free suite needs nothing and is green on a fresh clone:

mvn test

Tests that need Oracle are gated: with no database reachable they *skip* rather than fail. To point them at your own instance, copy the templates — the real files are gitignored and never leave your machine:

cp src/test/resources/test-boxes.properties.template src/test/resources/test-boxes.properties

cp Scripts/tns/tnsnames.ora.template Scripts/tns/tnsnames.ora cp Scripts/boxes.env.template Scripts/boxes.env

Per setting, an environment variable (MCPDBWIZARD_TEST_HOST, …) always wins over the file, which is how a run selects one server over another.

A third tier links against generator output: Scripts/testrun_current.sh regenerates code from a set of configs and compiles it, and a family of harnesses then drives that code against a live database.

That tier is not part of this repository, and neither are the schemas it needs. The configs introspect Oracle schemas whose structure is not ours to publish — some of it came from customer work years ago — and a config *enumerates* the schema it points at, so the configs cannot ship either. The harnesses go with them: they name those schemas' tables and routines, and they only compile against a regenerated tree that cannot exist here.

What that costs you: nothing to run the generator, and nothing to run the suite. The database-free tests are complete and green on a fresh clone; the gated live tests skip. What you do not get is a ready-made corpus to regenerate against. Scripts/check_provisioning.sh stays, and will name the exact objects a config expects, which is the place to start if you build your own.

examples/generated-output/ shows what the generator emits, with no database at all.

API documentation

[API docs for `com.mcpdbwizard.pub`](https://srmadscience.github.io/mcpdbwizard-open/)

That is the runtime library generated code links against, and the only package documented — the generator's own internals are implementation, and publishing them would bury the part you call. The package summary explains what to reach for, and carries the compatibility contract: signatures there are load-bearing for every program this generator has produced, so they gain methods and do not change them.

The same pages are on the project site at mcpdbwizard.com/javadoc. Both are regenerated from source on publish rather than copied from one another.

Locally, mvn javadoc:javadoc writes them to target/reports/apidocs/. It runs with failOnWarnings, so a broken @link fails the build rather than shipping a dead cross-reference.

Known issues

[Known issues](https://mcpdbwizard.com/docs/known-issues/) — what is wrong, what a caller actually sees when it bites, and the workaround for each. Most of them do not announce themselves: a record whose JSON keys are the generated field names rather than the column names, a VECTOR routine parameter that takes a dense array only, a config whose tool count outgrows Oracle's open_cursors.

Every open entry there is also an issue in this repository, linked from the page. Read it before filing — and if one of them is biting you, say so on its issue rather than opening a new one. Three of those entries are documented rather than fixed *because nobody has asked*, so a comment is the whole difference between "nobody has ever needed this" and "somebody does".

See CONTRIBUTING.md. One thing to run before opening a pull request:

Scripts/export/check-export-clean.sh

It fails if a private hostname, a credential or a jar has crept into the tree.
