Tools (7)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • check_connection

    Check if the database and Service Layer connections are active and alive. Pings DirectDb (SELECT query) and Service Layer (GET request) independently. No parameters required. Reports status for both connections.

  • connect_database

    Description is built at runtime.

  • execute_service_layer

    Execute a read-only OData GET against the currently connected SAP Business One Service Layer. Writes go through execute_service_layer_write. Denied when the connected profile's slAllowedMethods (printed by connect_database) omits GET. Query options are allowed; absolute URLs, Login/Logout and $batch are denied.

  • execute_service_layer_write

    Execute a guarded OData write (PATCH, POST or DELETE) against the currently connected SAP Business One Service Layer. These are real writes to the company database. The verb must be in the connected profile's slAllowedMethods, and database must equal the connected Service Layer database exactly — connect_database prints both. A mismatch is denied. Approval follows the profile's slWriteApproval, also printed by connect_database. "elicitation" (default): the server asks the user through an MCP approval form; clients without form elicitation cannot write. "client" or "none": the server executes…

  • execute_service_layer_write_unattended

    Execute a guarded OData write (PATCH, POST or DELETE) with NO approval of any kind, for development companies. Denied unless the connected profile has slWriteApproval "none" (printed by connect_database); otherwise use execute_service_layer_write. These are real writes to the company database. Every other rule of execute_service_layer_write applies unchanged: database must equal the connected Service Layer database, the verb must be in slAllowedMethods, the same endpoint shapes are enforced, MCP_DRY_RUN previews and MCP_SL_WRITES_ENABLED=false disables it.

  • execute_sql

    Execute a raw SQL statement against the currently connected database. All SQL, whether written by the user or generated by you, goes through the same server-side validation. IMPORTANT: Before calling this tool, you MUST confirm which database the user intends to query. If the user has not explicitly stated the target database in their message, ASK them first. Do NOT assume the currently connected database is the intended target. READ-ONLY: only SELECT (and read-only DO BEGIN...END blocks) execute. Data-changing statements are blocked server-side. If the user needs a write (INSERT/UPDATE/DEL…

  • get_schema_info

    Retrieve metadata about tables, columns, or procedures in the currently connected database. Read-only. Use this to explore the schema before writing queries. For "columns": provide the table name in "filter". For "tables"/"procedures": filter is optional (LIKE pattern). IMPORTANT: Before calling this tool, you MUST confirm which database the user intends to query. If the user has not explicitly stated the target database in their message, ASK them first. Do NOT assume the currently connected database is the intended target.
