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 3.1/5 across 1 of 1 tools scored.
With only one tool, there is no risk of ambiguity. The tool's purpose is clearly defined in its description.
The single tool name 'invoke' follows a verb-based pattern, and with only one tool there are no inconsistencies.
A single tool for a server named 'llm-observability-orchestration' feels thin. While it serves a specific purpose, the scope suggests more tools would be appropriate.
The server's name implies orchestration and observability capabilities, yet only provides a single invocation tool. Missing tools for tracing management, data retrieval, or workflow orchestration make it severely incomplete.

Tool Definition Quality
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden for behavioral disclosure. It mentions optional tracing but does not discuss side effects, authentication, rate limits, or what happens to the system. Insufficient for a tool with no annotation support.
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?
Single sentence, highly concise, front-loaded with the action. No redundant words.
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?
The description covers the core purpose but lacks details about the expected input format (beyond vague 'A2A message') and output. Without output schema, the agent cannot anticipate the tool's return value, which hinders completeness.
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?
Schema description coverage is 100%. The parameter description in the schema ('JSON request... same as A2A message') provides some meaning. The tool description adds no further elaboration, so the baseline score of 3 is appropriate.
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?
The description clearly states the action (run a prompt) and the resource (LangChain chain over Gemini on Vertex AI with optional tracing). It is specific but lacks mention of the output. No siblings exist, so differentiation is not needed.
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?
No guidance on when to use this tool vs alternatives or what prerequisites exist. The description does not provide context for the agent to make informed decisions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

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
