Glama MCP Gateway
Connect through Glama MCP Gateway for full control over tool access and complete visibility into every call.
Full call logging
Every tool call is logged with complete inputs and outputs, so you can debug issues and audit what your agents are doing.
Tool access control
Enable or disable individual tools per connector, so you decide what your agents can and cannot do.
Managed credentials
Glama handles OAuth flows, token storage, and automatic rotation, so credentials never expire on your clients.
Usage analytics
See which tools your agents call, how often, and when, so you can understand usage patterns and catch anomalies.
Tool Definition Quality
Average 4.3/5 across 1 of 1 tools scored.
There is only one tool, so there is no chance of selecting the wrong tool. The single purpose is clearly defined.
The one tool name, szukaj_api, follows a consistent verb_noun pattern (search + api). With only one tool, there are no mixed naming conventions to create confusion.
A single tool is below the typical 3–15 range, but the server is intentionally a narrow read-only catalog search. The one tool handles both full listing and filtered searching, so the count is reasonable for the purpose.
The tool covers both browsing the full catalog and searching with filters, and returns key metadata such as jurisdiction, authorization, and format. There are no obvious missing operations for a read-only API catalog interface.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Brak adnotacji, więc opis bierze na siebie ciężar ujawnienia zachowania. Informuje o zwracanych polach oraz o przypadkach brzegowym pustego zapytania, co jest istotne dla agenta. Nie wspomina o ewentualnych limitach ani skutkach ubocznych, ale wyszukiwanie w katalogu jest operacją tylko do odczytu.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Dwa zwięzłe zdania, bez powtórzeń i szumu informacyjnego. Główna akcja jest podana na początku, a dalsze szczegóły dotyczą wyniku i przypadku brzegowego, co zapewnia dobrą czytelność i szybkie przetworzenie przez agenta.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Proste narzędzie wyszukujące z zerowymi parametrami wymaganymi i pełnym schematem parametrów nie potrzebuje dłuższego opisu. Informacja o zwracanych danych jest wystarczająca nawet bez output-schema, więc agent ma wszystko, czego potrzebuje do poprawnego wywołania.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Parametry są w 100% udokumentowane w input-schema, więc opis nie musi ich powtarzać. Tekst dodaje tylko ogólną informację o filtrach i zachowaniu pustego zapytania, ale nie wnosi szczegółowej semantyki wykraczającej poza to, co już znajduje się w definicjach parametrów.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
Opis używa konkretnego czasownika „Przeszukuje” i jednoznacznego zasobu (katalog openAPI.pl). Dodatkowo precyzuje, co zwraca: wpisy z linkiem do dokumentacji, jurysdykcją, typem autoryzacji i formatem, dzięki czemu cel narzędzia jest jasny.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Kontekst użycia jest wyraźny: narzędzie służy do wyszukiwania oficjalnych, publicznych API rządowych. Brak narzędzi rodzeństwa zmniejsza potrzebę wykluczeń; opis nie podaje wprost, kiedy nie używać, ale nie jest to tu konieczne.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Claim this connector by publishing a /.well-known/glama.json file on your server's domain with the following structure:
{
"$schema": "https://glama.ai/mcp/schemas/connector.json",
"maintainers": [{ "email": "your-email@example.com" }]
}The email address must match the email associated with your Glama account. Once published, Glama will automatically detect and verify the file within a few minutes.

The connector status is unhealthy when Glama is unable to successfully connect to the server. This can happen for several reasons:
The server is experiencing an outage
The URL of the server is wrong
Credentials required to access the server are missing or invalid
If you are the owner of this MCP connector and would like to make modifications to the listing, including providing test credentials for accessing the server, please contact support@glama.ai.
