I use the official GitHub MCP server ( https://github.com/github/github-mcp-server ). Surprisingly, Bolt converts the LLM tool call parameter ( page ) from a number ( 1 ) to a boolean value ( true ). LLM tool call: {"page":1,"query":"[REMOVED]","perPage":10} MCP request: {"id":"9ED950C9-78F2-4FC4-92A6-CA8AA8E3B8F3","method":"tools\/call","params":{"name":"search_repositories","arguments":{"perPage":10,"query":"[REMOVED]","page":true}},"jsonrpc":"2.0"} MCP response: {"jsonrpc":"2.0","id":"9ED950C9-78F2-4FC4-92A6-CA8AA8E3B8F3","result":{"content":[{"type":"text","text":"parameter page is not of type float64, is bool"}],"isError":true}} Tool schema: { "properties" : { "page" : { "minimum" : 1, "description" : "Page number for pagination (min 1)", "type" : "number" }, "query" : { "type" : "string", "description" : "Search query" }, "perPage" : { "type" : "number", "minimum" : 1, "description" : "Results per page for pagination (min 1, max 100)", "maximum" : 100 } }, "type" : "object", "required" : [ "query" ] }
