sap-sybase-mcp-server-by-cdata
Provides a read-only MCP (Model Context Protocol) server that wraps a CData JDBC Driver for SAP Sybase, exposing Sybase data as SQL-queryable tools (get_tables, get_columns, run_query) over stdio for use by local MCP clients (e.g., Claude Desktop).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
MCP runs locally over stdio, reducing exposure over the network, but there is no documented transport/security model at the MCP layer. Authentication is handled by the CData JDBC driver via connection string in a local .prp; the README does not describe how secrets are protected (file permissions, logging behavior). The MCP tools expose run_query for SQL SELECT; while intended read-only, allowing free-form SQL increases risk of data overexposure if used with overly-permissive database credentials. Rate limiting and authorization scopes are not documented.
⚡ Reliability
Best When
You have local access to run a Java MCP server on the same machine as your MCP client, and you want LLM-assisted read-only querying of Sybase data without writing SQL.
Avoid When
You need a hosted/network MCP endpoint, fine-grained authorization per tool/user, documented rate-limit behavior, or you cannot install/run the required CData JDBC driver components locally.
Use Cases
- • Ask natural-language questions over SAP Sybase (Sybase) data using an MCP-capable desktop client
- • Explore available tables and columns from the Sybase data model
- • Run read-only SQL SELECT queries to retrieve live operational data
Not For
- • High-trust production deployments requiring a network-exposed service with hardened transport and auth boundaries
- • Use cases needing guaranteed idempotency or safe write operations (project is explicitly read-only)
- • Clients that cannot run the MCP server locally via stdio
Interface
Authentication
The MCP server itself is configured via a local .prp that includes the JDBC URL; authentication is delegated to the underlying CData JDBC driver. The README notes that if the data source uses OAuth, authentication is performed in a browser, but it does not document MCP-level auth scopes.
Pricing
Repo is MIT-licensed, but CData JDBC Driver licensing is required per README (trial or license key). No pricing for this MCP server is provided in the README.
Agent Metadata
Known Gotchas
- ⚠ Server uses stdio, so it can only be used with clients running on the same machine
- ⚠ Claude Desktop may need a full quit/restart to load newly configured MCP servers
- ⚠ Queries are provided as raw SQL SELECT statements in run_query; agents must be careful to avoid overly broad queries and to use the expected quoting/column/table naming conventions
