postgres-sql
About
A postgres-sql tool executes a pre-defined SQL statement against a Postgres
database. It’s compatible with any of the following sources:
The specified SQL statement is executed as a prepared statement,
and specified parameters will inserted according to their position: e.g. 1
will be the first parameter specified, $@ will be the second parameter, and so
on. If template parameters are included, they will be resolved before execution
of the prepared statement.
Example
Note: This tool uses parameterized queries to prevent SQL injections. Query parameters can be used as substitutes for arbitrary expressions. Parameters cannot be used as substitutes for identifiers, column names, table names, or other parts of the query.
tools:
search_flights_by_number:
kind: postgres-sql
source: my-pg-instance
statement: |
SELECT * FROM flights
WHERE airline = $1
AND flight_number = $2
LIMIT 10
description: |
Use this tool to get information for a specific flight.
Takes an airline code and flight number and returns info on the flight.
Do NOT use this tool with a flight id. Do NOT guess an airline code or flight number.
A airline code is a code for an airline service consisting of two-character
airline designator and followed by flight number, which is 1 to 4 digit number.
For example, if given CY 0123, the airline is "CY", and flight_number is "123".
Another example for this is DL 1234, the airline is "DL", and flight_number is "1234".
If the tool returns more than one option choose the date closes to today.
Example:
{{
"airline": "CY",
"flight_number": "888",
}}
Example:
{{
"airline": "DL",
"flight_number": "1234",
}}
parameters:
- name: airline
type: string
description: Airline unique 2 letter identifier
- name: flight_number
type: string
description: 1 to 4 digit number
Example with Template Parameters
Note: This tool allows direct modifications to the SQL statement, including identifiers, column names, and table names. This makes it more vulnerable to SQL injections. Using basic parameters only (see above) is recommended for performance and safety reasons. For more details, please check templateParameters.
