unsubscribeCancel a subscription by id. Ownership is enforced — you can only cancel your own subscriptions. The row is deactivated (not deleted) so its historical events stay available via recent_alerts.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond annotations (destructiveHint=false), description explains behavioral nuance: 'The row is deactivated (not deleted) so its historical events stay available via recent_alerts.' Adds valuable context about side effects.
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?
Two sentences, no wasted words. Front-loaded with core purpose, then adds ownership and behavioral details efficiently.
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?
For a simple one-parameter tool with no output schema, description fully covers purpose, constraints, and side effects. No gaps for agent invocation.
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 coverage is 100%, so baseline is 3. Description adds no further parameter details beyond schema (e.g., format or constraints), but this is adequate.
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?
Description clearly states the action 'Cancel a subscription by id' with specific verb and resource. It distinguishes from siblings like 'subscribe' and 'list_subscriptions'.
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?
Explicitly states ownership enforcement: 'you can only cancel your own subscriptions.' Provides clear context on when to use but does not mention alternatives or when not to use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Many tools have distinct purposes, but there is notable overlap between ask_pipeworx, ask_pipeworx_grounded, and deep_research, all serving data retrieval. Similarly, the Polymarket betting tools (bet_research, polymarket_arbitrage, polymarket_edges, etc.) share a domain, causing potential confusion for an agent.
Tool names follow no consistent pattern: snake_case (ai_visibility_check), camelCase-like (bet_research, compare_entities), and noun-first (entity_profile, recent_changes) are mixed. The lack of a uniform verb_noun or other convention makes it harder to predict tool names.
35 tools is excessive for a server named 'Osrm,' which suggests a focused routing engine. The actual tool set spans routing, data query, betting, entity resolution, and memory, indicating an overbroad scope that dilutes coherence.
The data query and betting tools are relatively comprehensive, but the routing side is minimal (missing isochrones, alternative routes). Gaps exist in general web search and coverage of other prediction markets. The server doesn't fully cover either the implied routing domain or the broader data/betting domain.
